Find the measure of the angle indicated in bold (8x+10)

Step-by-step explanation:

Note that the angle with the measurement (8x + 10) & (10x - 10) are corresponding, which means that the would have the same measurements. Set the two equal to each other, and solve for x.

(8x + 10) = (10x - 10)

Isolate the variable (x). Subtract 10 & 10x from both sides.

8x (-10x) + 10 (-10) = 10x (-10x) - 10 (-10)

8x - 10x = -10 - 10

Simplify.

-2x = -20

Isolate the variable (x). Divide -2 from both sides.

(-2x)/-2 = (-20)/-2

x = -20/-2

x = 10

10 is your measurements for variable x.

Plug in 10 for x in both of the expressions:

10x - 10 = 10(10) - 10 = 100 - 10 = 90

8x + 10 = 8(10) + 10 = 80 + 10 = 90

Both measurements = 90°

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
