what's the question your tryna figure out
Answer:
a
Step-by-step explanation:
it is the same angle
Answer:
B. 88.8
Step-by-step explanation:
let x represent class y
(x+71.2)/2=80 multiply each side by 2
x+71.2=160 subtract 71.2 by both sides
x=88.8
or
trial an error
replace x with each of the numbers and see if it plugs in.
example:
(80.5+71.2)/2=80
151.7/2=80
75.85=80?
false. incorrect
another example:
(88.8+71.2)/2=80
160/2=80
80=80?
true. correct
Answer:
Angle A: 60
Angle B: 30
Angle C: 90
Step-by-step explanation:
To figure out the angles, you need to set up an equation:
180 = x + x + 30 + x + 60
Add like terms:
180 = 3x+ 90
Solve for x
90 = 3x
divide by 3 to get x
30 = x
So, x is 30, and angle a is angle b plus 30, which is 60. angle c is x plus 60, which is 90.
