The answer is 58, because 2/5 is equal to 0.4, and 0.4 multiplied by 145 is 58.
Answer:
base : 30 cm
height : 20 cm
perimeter : 92 cm
Area : 400 cm
Step-by-step explanation:
base : 30 cm
height : 20 cm
perimeter : 27 + 30 + 25 + 10
: 92 cm
Area : (1/2 ( a + b) ) x h
: (1/2 ( 10 + 30) ) x 20
: (20) x 20
: 400 cm
There 2 angles are corresponding angles, in which the angle measurements would have the same degree.
Set the two angles equal to each other, and solve for x.
7x - 1 = 8x - 14
Isolate the x. Subtract 8x from both sides, and add 1 to both sides
7x (-8x) - 1 (+1) = -14 (+1)
7x - 8x = -14 + 1
-x = -13
Isolate the x. Divide -1 from both sides
(-x)/-1 = (-13)/-1
x = -13/-1
x = 13
13 is your answer for x.
