Answer:
440
Step-by-step explanation:
You can write the problem statement in math terms as ...
88 = 0.20 × (what number)
To solve this, divide by the coefficient of the variable, 0.20.
88/0.20 = (what number)
440 = (what number)
The number you're looking for is 440.
_____
Of course you know that 20% = 20/100 = 0.20.
(% is a shorthand way to write /100.)
150+(.10)x+x=200
.10x+x=50
1.10x=50
x=45.45454545

Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α
