Answer:
x = 55
y = 60
Step-by-step explanation:
If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary. So E and G are supplementary, and H and F are supplementary.
x + 15 + 2x = 180
3x + 15 = 180 combine like terms
3x = 165 subtract 15 from both sides
x = 55 divide both sides by 3
y + 3y - 60 = 180
4y - 60 = 180 combine like terms
4y = 240 subtract 60 from both sides
y = 60 divide both sides by 4
Answer:
a = 324
Step-by-step explanation:
9=1/27 a -3
value of a = ?
9=(1/27) a -3
9 + 3 = (1/27) a
12 = (1/27) a
12 x 27 = a
a = 324
Answer:
2y
Step-by-step explanation:
Answer:
total ground and wall angle is 90°
beam angle with ground= 51
beam angle with wall =39
because total angle=angle with ground + angle with wall
angle with wall=total angle-angle with ground
angle with wall= 90-51=39
