Answer:

the top angle is 48

the bottom right  angle is 42

Step-by-step explanation:

The sum of the angles of a triangle is 180

90 + 8x+7x = 180

Combine like terms

90 +15x = 180

Subtract 90 from each side

15x = 180-90

15x = 90

Divide by 15

15x/15 =90/15

x = 6

8x = 8*6 = 48  so the top angle is 48

7x = 7*6 = 42 so the bottom angle is 42

Solution given:

8x°+7x°+90°=180°[sum of interior angle of a triangle is 180°]

15x=180°-90°

x=90/15

x=6°

Turn both fractions into mixed fractions resulting in 75/2 and 5/2. Then turn them into decimals. 75/2= 37.5 and 5/2= 2.5. Then divide each other  37.5 / 2.5= 15. 15 is your answer. Hope it helped :)

How to find the length of the hypotenuse correct to one decimal place<br>​
hichkok12 [17]

Answer:

If you are provided with the lengths of two sides a triangle, you can find the third side using the Pythagorean Theorem: a^2+b^2=c^2.

Variable c represents the length of the hypotenuse, and variables a and b represent the lengths of the other two sides.
