∠A = 24°
∠B = 87°
∠A = 24°
Explanation:
The sum of angles in a triangle is 180 degrees
let measure of angle A = ∠A
∠B = 15 more than three times the measure of angle A
∠B = 15 + 3∠A
∠C = 45° more than the measure of angle A
∠C = 45° + ∠A
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
∠A + 15 + 3∠A + 45° + ∠A = 180
collect like terms:
∠A + 3∠A + ∠A + 15 + 45 = 180
5∠A + 60 = 180
5∠A = 180 -60
5∠A = 120
∠A = 120/5
∠A = 24°
∠B = 15 + 3∠A = 15 + 3(24)
∠B = 87°
∠C = 45° + ∠A = 45° + 24°
∠C = 69°
The two diagonals<span> are </span>equal<span> in length and bisect each other. Every </span>quadrilateral<span> with both these properties is a </span>rectangle<span>. A </span>rectangle<span> is rectilinear:which means its sides meet at right angles.</span>
B because they are equal parts
I believe it would be as following:
x+7>12
Here, x represents the unknown number. The symbol for no less than is greater than.
