An angle measures 70° more than the measure of its supplementary angle. What is the measure of each angle
jekas [21]

Answer:

55° and 125°

Step-by-step explanation:

Formulate an equation x + (x+70) = 180

Combine like terms to get 2x + 70 = 180

Subtract 70 on both sides to get 2x = 110.

Divide both sides by 2 to get x = 55.

Add 70 to 55 to get 125.

Check your answer by adding 55 + 125. It equals 180, so the angles are equal to 55 and 125.

Can some one plz help me?! The LATERAL Surface Area for the shape below is:
love history [14]

Answer:

430 cm2

Step-by-step explanation:

The Lateral Surface Area of it is equal to:

Area of ABCD + Area of A'B'C'D' + Area of ABB'A' + Area of DCC'D' + Area of ADD'A' + Area of BCC'B'

As ABCDA'B'C'D' is a rectangle prism, so that:

+) Area of ABCD = Area of A'B'C'D'

+) Area of ABB'A' = Area of DCC'D'

+) Area of ADD'A' = Area of BCC'B'

=> Total lateral surface area = 2. Area ABCD + 2. Area ABB'A + 2. Area ADD'A

As ABCDA'B'C'D' is a rectangle prism, so that we have: ABCD, ABB'A', ADD'A' are rectangles.

The formula to calculate the area of rectangle is: Area = Length x Width

We have:

+) Area ABCD = AB x BC =11 x 10 = 110 cm2

+) Area ABB'A = AB x AA' = 11 x 5 = 55 cm2

+) Area ADD'A = AA' x A'D' = 5 x 10 = 50cm2

Total lateral surface area = 2. Area ABCD + 2. Area ABB'A + 2. Area ADD'A

= 2 x 110 + 2 x 55 + 2 x 50 = 430 cm2
