The 2 angles given are vertical angles, which mean they are the same.
So we have: 3x +1 = 64
Subtract 1 from each side:
3x = 63
Divide both sides by 3:
X = 63 / 3
X = 21
The answer is A.
Answer:
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
Step-by-step explanation:
In a triangle, the sum of all inside angles must be 180 degrees.
In this question:
The inside angles are: x, x + 50 and 180 - 3x.
Then
x + x + 50 + 180 - 3x = 180
2x - 3x = -50
x = 50
So
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
Answer:
The lateral surface area of a prism is the sum of the areas of its lateral faces. The total surface area of a prism is the sum of the areas of its lateral faces and its two bases.
There are 3 sides and 3 angles per shape, because they are both triangles. hope this helped you out!!!
Step-by-step explanation:
f(x)=(2×2)-3x+20
0=4-3x+20
0=-3x+24
3x=24
×=24÷3
x=8
