Lets x = missing angle
x = 180 - (60+80)
x = 180 - 140
x = 40
answer
40
Answer:
x = 11°
Angle WVZ = Angle XVY = 84°
Step-by-step explanation:
Angle WVZ = Angle XVY
Vertical opposite angles
9x - 15 = 5x + 29
4x = 44
x = 11°
Angle WVZ = Angle XVY = 9(11) - 15
= 99 - 15 = 84°
WVY is probably a typo, but if needed:
Angle WVY is 180° because they form a straight line
Yes the answer is correct
Answer:
paper left = 168.56 units²
Step-by-step explanation:
first, figure the area of the square:
area of square = 28x28 = 784 units²
second, figure the area of the circle:
radius = 1/2of 28 = 14
area of circle = Pi x Radius² = (3.14)(14)² = 615.44 units²
subtract area of circle from area of square:
784 - 615.44 = 168.56 units²
There are 3 shapes present.
Triangle - 2
Circle - 4
Square - 2
The ratio of triangles to circles: 2 triangles to 4 circles ⇒ 2/4
2/4 simplified to 1/2.
