M∠1=45° and m∠3=65° what is m∠4? 2. in right △abc with right angle b, m∠a=(3x−8)° and m∠c=(x−2)°. what is m∠a? 47° 67° 25° 92

In Right Δ ABC with right angle B,

∠A=(3 x -8)°, ∠B=90°, ∠C=(x-2)°

∠A+∠B+∠C=180°[∠ sum property of triangle]

3 x-8+90 + x-2=180

Adding and subtracting like terms

4 x-10+90=180

4 x+80=180

4 x=180-80

4 x=100

x=100/4

x=25°

∠A=3×25-8=75-8=67°

the expected value of the random variable : 0, 1 and 2
