Answer:
D. 60, 45,75
Step-by-step explanation:
For options C and D
For a triangle the sum of the angles must always be equal to 180 degrees
So 180 ≠45+45+80
and
60 +45+ 75= 180
For option A and B
The length of the longer side is equal to the square root of the sum of squares of the other two sides in a triangle.
According to Pythagorus theorem
hypotenuse²= base² + perpendicular²
c²= a²+ b²
90²= 50² + 35²
8100= 2500+1225
8100≠3725
95²= 60²+ 25²
9025= 3600+ 625
9025≠4225
Therefore only D is the correct option
Two 2d shapes make a cylinder.
A square or rectangle for the tube in the middle.
And circles on the ends
Answer: green angle = 76 degree
Solution:
We can use interior angle properly of a triangle to find it.
Exterior angle = sum of interior angles
So, 116 = 4x + (7x + 6)
11x + 6 = 116
11x = 116 - 6
11x = 110
x = 110/11 = 10
So, angles = 4 x 10 = 40
7 x 10 + 6 = 70 + 6 = 76
Green angle: 76 degree
Ok this is easy so since the formula for a cylinder is pie(r to the 2nd power) times h it’s like this——-
3.14(5 to the 2nd power) 0.25
3.14(25)0.25
78.5(0.25)
=19.625
