Since the interior angles of a triangle equal 180°, then 180-45=135.
Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.
Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.
However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180

Step-by-step explanation:
1 - 2 + 10 o lw. First find a common denominator. 3 * 5. After cross reducing, multiply across ... Divide the fraction to get a decimal answer. 21 into a an. Jinit. 5 = 1.25 ... 3 = -x +8. -8 = -8. = -5 = -X. =-1(-5) = -x (-1). = 5 = x. Set up a ratio, and cross ... Combine like terms, and solve for x. Divide both sides by 2. = x= 20. = 5-1">4.
