Answer:
m∠ABC = 110°
Step-by-step explanation:
By the property of exterior angle of a triangle,
"Exterior angle of a triangle is equal to the sum of two opposite interior angles"
m∠BAC + m∠ABC = 135°
25° + m∠ABC = 135°
m∠ABC = 135° - 25°
= 110°
Therefore, measure of angle ABC is 110°.
Answer:
(-∞,∞) or {y|y∈R}
Step-by-step explanation:
Answer:
r=−1/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(r−10)=−51
(5)(r)+(5)(−10)=−51(Distribute)
5r+−50=−51
5r−50=−51
Step 2: Add 50 to both sides.
5r−50+50=−51+50
5r=−1Step 3: Divide both sides by 5.
5r/5=−1/5
r=−1/5
Answer:
The answer to your question is: 6x + 5
Step-by-step explanation:
(8x² - 5x -7) - (9x² - 3x -5) + (x+7)(x + 1)
8x² - 5x - 7 - 9x² + 3x + 5 + x² + 8x + 7
9x² - 9x² - 5x + 11x + 12 - 7
6x + 5
