Question

Solve for x!! ( picture )

Answer 1

21) c

22) c

Explanation:

21:

subtract 11 from 21 to get the measures for the the bottoms of both triangles combined which is 10

then divide 10 by 2 to get the measures to get the bottom of each individual triangle.

once you have that you can use Pythagorean theorem which is a squared plus b squared plus c squared and c represents the hypotenuse to find x which is 12.

22:

for this one, you can use Pythagorean theorem to get the bottom measurement of one triangle which is 9 then multiply that by 2 since there's two triangles to get 18. then since you're missing the middle line you just look at the top and it says that the measurement for that line is 10 so you would just add 10 to 18 to get 28.

Answer 2

Answer:C

Explanation:

to get adjacent 21-11=10

10/2=5

adjacent=a=5

Hypotenuse=h=13

Opposite=x

Using Pythagoras principle we can find x

x=√(h^2-a^2)

x=√(13^2-5^2)

x=√(13x13-5x5)

x=√(169-25)

x=√(144)

x=12
