which similarity theorem can be used to prove the two triangles below similar ?
A: sss similarity theorem
B. aa similarity theorem
C. sas similarity theorem
D. not similar
The similarity theorem that proves the two given triangles are similar is: B. AA similarity theorem.
Recall:
The angle-angle similarity theorem (AA) states that if two angles in one triangle are of the same measure with two corresponding angles in another triangle, both triangles are similar to each other.
In the image given:
[tex]\angle F[/tex] in [tex]\triangle ETF[/tex] is congruent to [tex]\angle U[/tex] in [tex]\triangle VTU[/tex] ([tex]\angle F = \angle U = 78[/tex])
[tex]\angle ETF = \angle VTU[/tex] (vertical angles are equal)
This implies that two angles in [tex]\triangle ETF[/tex] are congruent to two corresponding angles in [tex]\triangle VTU[/tex].
Therefore, both triangles can be proven to be similar by the angle-angle similarity theorem (AA).

what does y = 3x + 5 look like on a graph?
What does a=? b=? Angle B=?
Answer:
If you were solving the right triangle, it would be:
m∠A = 46°
m∠B = 44°
m∠C = 90°
AB = 32
BC ≈ 23
AC ≈ 24
Step-by-step explanation:
To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:
m∠A = 46° (given)
m∠B = x
m∠C = 90° (given)
180 - (46 + 90) = x
180 - 136 = x
44 = x
m∠B = 44°
To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.
Recall that:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
So:
sin46 = BC/32
BC = 32 (sin46)
BC ≈ 23
tan46 = BC/AC
AC = BC/tan46
AC = (23.01887361...) (tan46)
AC ≈ 24

Step-by-step explanation:
use the graph to estimate the solution to the system of equations shown.
A. x=5 1/2, y= 3 1/4
B. x= -3 1/2, y= -5 1/4
C. ×= 3 1/2, y= 5 1/4
D. x= -5 1/2, y= -3 1/4
==============================================================
Explanation:
The solution occurs where the two lines intersect. From this intersection point, draw a vertical line upward until you reach the x axis. We arrive somewhere between -5 and -6. A good estimate is to say that we're at the midpoint, so x = -5 & 1/2 is one possible estimate
Since only choice D has this x value, this must mean choice D is the answer. The y coordinate of y = -3 & 1/4 seems to fit as well since we can draw a horizontal line from the point of intersection to the y axis, and arrive somewhere just a little below -3.

I need to evaluate h(3)
Answer:
h(3) = - 1
Step-by-step explanation:
To evaluate h(3), that is x = 3 in the interval x ≥ 1 , then
h(x) = - x + 2 , thus
h(3) = - 3 + 2 = - 1
Then h(3) = - 1

what is 153.87 divided by 23
The result of dividing 153.87 by 23 is approximately 6.6847826087.
Given that we need to determine that what is 153.87 divided by 23,
To justify this answer, we can perform the division calculation:
6.6847826087
--------------
23 | 153.87
138
-----
158
138
-----
208
207
-----
10
The division is performed by dividing 23 into 153.87. We start by dividing 23 into 153, which gives us 6 as the whole number part of the quotient. We then subtract 138 (6 multiplied by 23) from 153, which leaves us with a remainder of 15.
To obtain a decimal approximation, we bring down the decimal point from the dividend (153.87) and continue the division process.
We add a zero after the decimal point in the dividend and divide again. This time, 23 goes into 158 (the new dividend) 6 times, giving us a partial quotient of 0.6.
The remainder is 158 minus 138 (6 multiplied by 23), which equals 20.
We bring down another zero and continue dividing.
23 goes into 208 (the new dividend) 9 times, resulting in a partial quotient of 0.69. The remainder is 208 minus 207 (9 multiplied by 23), which equals 1.
At this point, we can either stop or continue dividing to obtain more decimal places.
Therefore, the result of dividing 153.87 by 23 is approximately 6.6847826087.
