Answer:
angle = 72°
complement = 18°
Step-by-step explanation:
x = (90-x) / 4
cross-multiply to get:
4x = 90 - x
5x = 90
x = 18
<h3>
Solution (a):</h3>
- Area of rectangle = LB
- => Area of rectangle = 18 x 36
- => Area of rectangle = 648 in²
<h3>
</h3><h3>
Solution (b):</h3>
<u>Since the two triangles are equal (as said in the question):</u>
- => Area of triangles: 2(1/2 x 6 x 18)
- => Area of triangles: 6 x 18
- => Area of triangles: 108 in²
<h3 /><h3>Solution (c):</h3>
<u>Subtract the area of the triangles from the area of the rectangle.</u>
- 648 - 108 = Area of trapezoid
- => 540 in² = Area of trapezoid
Answer:
2+x
Step-by-step explanation:
Sum= addition
If the number is not provided we always include a variable and the most common one is X never use t, o, i, l, because you might confuse yourself because they look like numbers when they are variables.
Answer:
75

Answer:
Step-by-step explanation:
20% of the eggs broke....25% were reserved for the guests....thats 45%
the remaining 22 eggs were consumed by family members...
so if 45% consisted of broken eggs and reserved eggs, then 55% were consumed by family members....and there were 22 eggs consumed by family.
so 55% of all the eggs = 22 eggs
0.55x = 22
x = 22 / 0.55
x = 40 eggs in the basket
20% of the eggs broke......20% of 40 = 0.20(40) = 8 eggs broke
25% were reserved.....25% of 40 = 0.25(40) = 10 eggs reserved
