This is a diffficult question was there a chart
Answer:
Right angles is 90° so 90°+30°=120°.A straight line is 180°. So you do 180°-120° which is 60. So A=60°
Triangle= 180 degrees
Angle = 37.5 degrees
Supplement angle = 105 degrees
If you multiply the angle (37.5) by 2 and then add 30, it gives you 105. Then add 37.5 twice to make up the other two angles of the triangle and it gives you 180 total degrees as a triangle should.

Answer:
Step-by-step explanation:
Part A
9x^2 + 24x + 16
= (3x + 4)(3x + 4)
length of each side = 3x + 4 units.
Par B
16x^2 - 25y^2
= (4x + 5y )( 4x - 5y)
length = 4x + 5y and width = 4x - 5y
