The answer is letter a. m∠BAD = 108.42°

The solution is as follows:
If m∠BAC = 40.62° and m∠BCA = 30.96°, then
m∠CBA = 180° - m∠BCA - m∠BAC
m∠CBA = 108.42°

Since m∠BAD = m∠CBA due to the parallelogram's property,
m∠BAD = 108.42°.

The hypotenuse of a right triangle is 52 in. One leg of the triangle is 8 in. More than twice the lenght of the other. What is t

shusha [124]

Call the short leg a. The Pythagorean Theorem says:

$a^2 + (8 + 2 a)^2 = 52^2$

$a^2 + 8^2 + 32 a + 4a^2 = 52^2$

$5a^2 + 32 a + 8^2-52^2 = 0$

$5a^2 + 32 a + (8-52)(8+52) = 0$

$5a^2 + 32 a - (44)(60) = 0$

$(5a + 132)(a - 20) = 0$

Only the positive root $a=20$ is relevant here.

The other side is $2a+8=48$

The perimeter is $20 + 48 + 52 = 120$ inches

Angle A and Angle B complementary angles. Angle A=(3x+6). Angle B=(3x+18) then find the measure of Angle A?

Pani-rosa [81]

Set up 3x + 6 = 45

The 45 is HALF of 90°
