angles in a triangle add up to 180
so x = 180 - ( 70 + 90 ) = 20
this is because the two other angles in the both of the identical triangles are 70 and 90
The answer would be 18 units I believe
2(7+2)
2(9)
18 units
Answer:
Theoretically, about 208 times, but it doesn't work in practice
4x the square root of three. A 30 60 90 right triangles’ legs are in a ratio of sqrt3/2:1/2:1. Since 1 is the part of the ratio representing the longest side, and our longest side is 8, our new ratio for our 30,60 90 triangle is 4xsqrt3:4:8. Since 4xsqrt3 is the longest leg (leg of length 4 being the other), 4xsqrt3 is the longest leg
Answer:
104.8 square feet
Step-by-step explanation:
To find the area of the figure, split it into two regular shapes: a rectangle and a semi-circle. Find the area of each and add it together.
Area of the rectangle is A = 8*10 = 80 square feet.
Are of semicircle is A = 1/2 πr² = 1/2 (3.1)(4²) = 1/2(3.1)(16) = 24.8 square feet.
Together the area is 80 + 24.8 = 104.8 square feet
