Area = side length²
Because it's a square, all of the side lengths are equal.
15 = s²
s = √(15)
s = √(15) inches
Hope this helps!
surface area of a triangle is 1/2 x base x height.
1/2 x 10 x 12 = 60 square inches.
there are 4 triangular sides: 60 x 4 = 240 square inches
area of the base = 10 x 10 = 100 square inches
total surface area = 240 + 100 = 340 square inches
answer: 340 square inches
Answer:
Step-by-step explanation:
Take the old value - the new value. then divide that by the old value.
1/3(a + b) = 60
a + b = 60 * 3 = 180
1/4(a - b) = 28
a - b = 28 * 4 = 112
a + b = 180
a - b = 112
---------------add
2a = 292
a = 292/2
a = 146
a + b = 180
146 + b = 180
b = 180 - 146
b = 34
so ur 2 angles are : 146 and 34
