Answer:
360°
Step-by-step explanation:
We need only remember that the sum of the measures of the interior angles of a triangle is 180°. Angle c and 112° form a pair of "straight angles," so they add up to 180°; as a consequence, Angle c = 180° - 112°, or 68°.
With two of the interior angles now known, we can calculate the third, Angle A: It is 180° less (51° + 68°), or 180° - 119°, or 61°.
That means that the measure of Angle B is 180° - 61° = 119°
Looking at the pair C and 112°, we identify the exterior angle as 112°.
Looking at the pair A and B, or 61° and 119°, we identify the exterior angle as 119°.
Finally, looking at the pair 51° and (180° - 51°), or
51° and 129°, we identify the exterior angle as 129°.
Then the sum of the exterior angles 129° and 119° and 112° is 360°.
Answer:
8.5%
Step-by-step explanation:
.17/2 = 0.085 or 8.5%
To convert 1.3 miles into inches we proceed as follows;
1 mile=63360 inches.
Therefore the number of inches in one mile will be as follows:
(1.3*63360)
=82,368 inches
Therefore, we conclude that our answer is 82,368 inches.
Answer:
39 degrees
Step-by-step explanation:
The angles in every triangle add to 180 degrees. This means 39 + 102 + x = 180.
Simplify and 141 + x = 180.
Solve for x by subtracting.
x = 180 - 141
x = 39
