Answer:
160, 160, 200, 200
Step-by-step explanation:
All you have to do is double the numbers.
Answer:
115°
Step-by-step explanation:
Knowing that the sum of all interior angles of any triangle is 180 degrees, we can find the measurement of the missing angle of the triangle. The calculation is 180 - 75 - 40 = 65. Then, notice that the blue angle and the missing angle are supplementary (linear; add up to 180 degrees). So we can find the blue angle's measurement by 180 - 65, so the answer is 115 degrees.
To find the x intercept, sub in 0 for y and solve for x...
-2x + 5y = -20
-2x + 5(0) = -20
-2x = -20
x = -20/-2
x = 10....so the x int is (10,0)
Answer:
180°
Step-by-step explanation:
The measures of the angles in the triangle shown are ...
81.87°, 60.26°, 37.87°
The sum of those measures is ...
81.87° + 60.26° + 37.87° = 180.00°
