Orlando is measuring the angles of a triangle. he measures the first two angles and gets 30° and 70°. what should be the measure of the third angle?
a) 50°
b) 80°
c) 100°
d) 260°

B) Third angle  80°.

Step-by-step explanation:

Given  : Orlando is measuring the angles of a triangle. He measures the first two angles and gets 30° and 70°.

To find : What should be the measure of the third angle.

Solution : We have given a triangle

One angle of triangle = 30° .

Second angle of triangle = 70°.

Let the third angle = x .

By the angle sum property : Sum of all the angle of a triangle is 180°.

Then, 30° + 70° + x = 180.

100 ° + x = 180°.

On subtracting both sides by 100

x = 180 - 100.

x = 80 degree.

Therefore, B) Third angle  80°.

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
