Answer:
s. -30
Step-by-step explanation:
All the angles in a triangle equal 180 so:
-2x - x + 90 = 180
add like terms
-3x + 90 = 180
subtracts 90 from both sides
-3x = 90
divide both sides by -3
x = -30
Answer:
this looks to be right to me
Answer:
16
Step-by-step explanation:
Let the number be x.
37.5% * x = 6
Convert percentage to decimal form:
Multiply both sides by 1000:
Divide both sides by 375:
Step-by-step explanation:
Area of first triangle = 1/2bh
the base of the triangle = the radius of the semi-circle = 2yd
height = 5yd
Area = 1/2(5yd)(2yd)
A = 5yd(yd)
A = 5y^2d^2 squared units.
since the second triangle also has the same dimensions as the first triangle
hence:
Area of the second triangle = 5y^2d^2 squared units.
Area of semi-circle = πr^2
Area = π(2yd)^2
A = 4πy^2d^2 squared units
Answer:
i believe the answer is x= 85
