Answer:
The value of x is 31°
Step-by-step explanation:
As we can see, the two angles at the bottom of the shape are base angles. These angles both form right angles which means they both have a measurement of 90°. Knowing this information, we can set up an equation to solve for x.
47 + (x + 12) = 90
47 + x + 12 = 90
Add 12 to 47.
59 + x = 90
Subtract 59 on both sides of the equation.
x = 31
The value of x is equal to 31.
Answer:
2x + 7y
Step-by-step explanation:
3x + 5y - x + 2y
Arrange it to be simplified easier,
3x - x + 5y + 2y
3x - x = 2x
5y + 2y = 7y
2x + 7y
No, the answer is not 2. The measure of angle 2 is 128°. You can find this by 26×4=104 -> 360-104=256 ->256÷2=128
Answer:
Base of figure A = 12 units
Step-by-step explanation:
Given:
Base of figure B = 15 units
Ratio of figure A to figure B = 4:5
Find:
Value of X
Computation:
X / 15 = 4 / 5
x = 4(15) / 5
x = 12
Base of figure A = 12 units
Answer:
15 ft.
Step-by-step explanation:
the ratio of the real room to the blueprint is 21/3.5, which simplifies to 6.
You have to multiply 6 by 2.5 to get 15
