Answer: 70-27x = 50-20x
Step-by-step explanation: First you do 7 x 10 which equals 70 then 7 x -3x equals -27x. Next you do 5 x 10 which is 50 next you do 5 x -4x equals -20x. So your answer is 70-27x = 50-20x
Step-by-step explanation:
Angles in a parallelogram are supplementary
Given:
Line l and line m are parallel.
Co-interior angles are (12x - 8)° and 104°.
To find:
The value of x.
Solution:
Sum of co-interior angles = 180°
12x° - 8° + 104° = 180°
12x° + 96° = 180°
Subtract 96° from both sides.
12x° + 96° - 96° = 180° - 96°
12x° = 184°
Divide by 12° on both sides.
x° = 7°
x = 7
The value of x is 7.
Answer:
circumference=>2πr
circumference= 119.32 cm
π = 3.14
r =?
119.32 = 2 × 3.14 × r
r = 119.32/6.28
r = 19 cm
so area = πr²
area = 3.14 × (19)²
area = 3.14 × 361
area = 1,133.54 cm²
