Because the two angles add up to equal 90, you would make an equation set to equal 90. On the other end you add the measures of your angles together because they are adding up to equal 90. This would look like 2x+5+35=90 and you solve from here. Add like terms making it 2x+40=90 then you subtract 40 from both sides making it 2x=50 and then divide by 2 on both sides which leaves you with x=25.
Answer:
43
Step-by-step explanation:
3x + 10 = 5x - 12
10 = 2x - 12
22 = 2x
x = 11
check:
33 + 10 = 55 - 12
43 = 43
correct
x = 11 so bring this into 3x + 10
we get 43

Answer:
100 ft long and 100 ft wide
Step-by-step explanation:
The building area is (40 ft)(20 ft) = 800 ft², so the area of the entire plot is ...
9200 ft² +800 ft² = 10000 ft² = (100 ft)²
The plot is square, so its side length is 100 ft.
