Answer:
both of these.will be solved by angle sum property which states that sum of all interior angles is 180 degrees
in a
one angle is 30 degrees
other is right angle means 90 degrees
total sum of these angles is 120
total sum of all angle must be 180 degrees
so the third angle is 60 degrees
in b
one angle is 45 degrees
other is a right angle means 90 degrees
total sum of these angles is 135
total sum of all angles must be 180 degrees
so the third angle is 45 degrees
hope this helps
have a good day
thanks for points

Answer:
(9,2)
Step-by-step explanation:
This is the point formula
80% of 150
step 1: 80% is a percentage, so you convert that into a decimal(just move it over two places)
step 2: Multiply .80(150)= 120
3/4 of 200
step 1: 3/4 is also 75%
step 2: 75% is a percent, so you change that into .75
step 3: Multiply .75(200)= 150
So 3/4 of 200 is bigger
Answer:
1. 519.75 cm^3
2. 19.22 cm^3
3. 613.6 cm^3
4. 1365.68 cm^3
Step-by-step explanation:
Hello again, similar to the other questions, these problems use the same formulas.
1. volume of a rectangular prism is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 4.5 x 7 x 16.5 and we get V = 519.75 cubic cm.
2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6.2 x 2 x 3.1 and we get V = 19.22 cubic cm
3. V = Bh, where B is the base area and h is the perpendicular height. Substitute known values into equation: V = 52(11.8). So, V = 613.6 cubic cm.
4. And again, V = Bh. Substitute given values into this equation: V = 79.4(17.2), which means V = 1365.68 cm^3
