Answer:
Option A is your answer ☺️☺️
Set up the equation like 4b+61=0, subtract 61 from both sides, and that'll be 4b=-61. Divide both sides by 4. b=15.25
Answer:
Y<u>></u>-x-5
Step-by-step explanation:
Answer:
a=15x; b=8x; c=13x
180°=a+b+c=15x+8x+13x=36x
=> x=180÷36=5
=> a=15×5=75°; b=8×5=40°; c=13×5=65°
Definitely B. Note how the powers of y are presented in descending order by power: y^8, y^7, y^1.
