the measure of the hypotenuse is? (side c)

Answers

answer: 25
explanation:
7² + 24² = c²
49 + 576 = c²
625 = c²
c = √625
c= 25

or just know some pythagorean triples

The answer is 25

Sooooo to find the hypotenuse you gotta use this formula: a^2+b^2=c^2.

change 4x - 5y = 10 into slope intercept form and graph

Answers

Answer:

Slope intercept form: y = 4/5x - 2

Step-by-step explanation:

(subtract 4x from both sides) -5y = -4x + 10

(divide everything by -5) y = 4/5x - 2

To graph, place a point at (0,-2), and then travel up 4 and over right 5 (or down 4 and to the left 5) to place the next point, then draw a line through the points

Help please :( I am stuck

Answers

Answer: We all hate it when we are stuck! The slope is -1/2.

Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.

It is -2/1 or just -2 because you must do the rise first which is counting downwards or upward then the run counting to the left or right

Side z is the hypotenuse, since it is opposite the right angle.

How do I solve for X? 20 points.

Answers

That triangle is isosceles, so the bottom two angles will always be equal. With that said, the equation will be 2(65), and that equals 130. After that, subtract 180-130, and that gives you x! In total, your calculations should look like this:
2(65)
180-130
x=50°

Step-by-step explanation:

[tex] \underline{ \underline{ \text{Given}}} : [/tex]

[tex] \angle \: ABC = 65 \degree[/tex]

[tex] \underline{ \underline{ \text{To \: Find}}} : [/tex]

Value of x

[tex] \underline{ \underline { \text{Solution}}} : [/tex]

[tex] \angle \: ACB = \angle \: ABC = 65 \degree[/tex] [ Base angles of isosceles triangle are equal ]

[tex] x \degree + 65 \degree + 65 \degree = 180 \degree[/tex] [ Sum of angle of a triangle ]

Hope I helped ! ♡

may you guys please help me (see picture)

Answers

Answer:

20

Step-by-step explanation:

We know that a triangle's angles must add up to 180 which means that

100+40+2x=180

solve for x

140+2x=180

2x=40

x=20

X in this problem equals 2. This is so because all angles in a triangle add up to equal 180°. You can use that fact to find that the missing angle should equal 40°. You can take that info and divide 40 by 20 which gives you 2. Hope this helps.

The angle of elevation from a boat to the top of a lighthouse is 50°.
If the boat is 150 feet from the base of the lighthouse, how tall is the lighthouse?
Round answer to the nearest foot.

Answers

9514 1404 393

Answer:

  179 ft

Step-by-step explanation:

The applicable trig relation is ...

  Tan = Opposite/Adjacent.

The height of the lighthouse is the opposite side of the right triangle. The adjacent side to the angle of elevation from the boat is the distance to the lighthouse base. Then ...

  tan(50°) = height/(150 ft)

  height = (150 ft)(tan(50°)) ≈ 178.76 ft

The height of the lighthouse is about 179 feet.

B. y = 7/3x + 5
C. y = –5x + 7
D. y = –1/2x – 7

Answers

B.

The first thing I do with a line is sub in 0 for x. This will give you the y intercept. On the graph, we can see that the y intercept is (0,5). So, the equation we use has to have an output of 5 if we plug in 0. The only one this applies to is equation B.

Answer:

Sally rode 4 kilometers more than her brother.

Step-by-step explanation:
