Answer:
x=13
Step-by-step explanation:
one angle of triangle=85
parallel lines and vertical angles
the second angle is 82:
sum of angles of the triangle=180
x+85+82=180
x+167=180
x=180-167
x=13
<span>X+2y=10 ----Eq.1
</span><span>x+y=6---------Eq.2
from Eq2.
x=6-y
Subtituting the value of X in the first equation
6-y+2y=10
6+y=10
y=4
Plug y=4 in equation 2.

</span>X= 2
Answer:
It would be Choice C, 12.4 feet.
Step-by-step explanation:
By using Pythagoras Theorem a² + b² = c²
c²- b²= a²
13²-4²=
169 - 16 = √153
√153 = 12.3693168769
12.3693168769 ≅ 12.4
