x = one angle
y = other angle
y = 15+x
complements add to 90 degrees
x+y = 90
substitute for y (15+x)
x + 15+x = 90
combine like terms
2x+ 15 = 90
subtract 15 from each side
2x = 75
divide each side by 2
x = 75/2
x = 37.5
y = x+15
y = 37.5 + 15
y =52.5
The two angles are 37.5 and 52.5
Since the shape is a square the sides are equal. Then we need to find x such that x * x = 169.
Sqrt(169) = 13
So x = 13
Answer:
243
Step-by-step explanation:
make 90% into a decimal
0.9
multiply 270 by 0.9 to get the answer of 243
Answer:
The area is 63.75 feet square
Step-by-step explanation:
Formula for area of a triangle is 1/2 × base × height
And we are given each of this variables in the question above
Therefore you just have to input those values to the formula
1/2×17/2×15
255/4
=63.75
Therefore the area of the triangle is 63.75 feet square
