Answer:

Smaller angle: 69 degrees

Larger angle: 111 degrees

Step-by-step explanation:

Supplementary angles= two angles that make up 180 degrees

x = smaller angle

x + x + 42 = 180 Add like terms

2x + 42 = 180 Subtract 42 on both sides

2x = 138 Isolate the variable by dividing 2 on both sides

x = 69

x = smaller angle, 69 degrees

x + 42 = larger angle, 111 degrees

Answer:

5/6

Step-by-step explanation:

1/3 + 1/2 is a simple addition fraction problem.

You'd find the LCM (lowest common denominator) which is 6. First, we'll take 1/3 which the denominator becomes 6. You see one side has been basically multiplied by 2, so you'd do it to both sides, giving us 2/6. Next, we do the same thing with 1/2. 2 -> 6 1 -> 3. 3/6. So finally, we have 3/6 + 2/6, which is 5/6.

Answer:

16) 62.8 m²

17) 19.4 m²

18) 103.5 m²

Step-by-step explanation:

The formula to find area of a circle is: $\pi r^{2}$ . To find radius, find the half of the diameter.

To solve number 16, first find the area of the unshaded circle using the formula: $\pi 4^{2}$ . This is also 3.14*16. Multiply to get 50.24 m². Now find the area of the larger circle using the formula: $\pi 6^{2}$ . This is also 3.14*36. Multiply to get 113.04 m². Now subtract 113.04 - 50.24 to get the shaded area or 62.8 m².

To solve number 17, first find the area of the square using the formula: side x side. In this case multiply: 5.25 x 5.25 to get 27.5625. Round to the nearest tenth to get 27.6 m². Now find the area of the circle using the formula: $\pi 2.625^{2}$ . This is also 3.14*2.625. Multiply to get 8.2425. Round to the nearest tenth to get 8.2. Subtract 27.6 - 8.2 to get 19.4 m².

To solve number 18, find the area of one unshaded circle using the formula: $\pi 1.75^{2}$ . This is also 3.14*3.0625. Multiply to get 9.61625. Round to the nearest tenth to get 9.6 m². Add 9.6 + 9.6 to find the area of both unshaded circles. You get 19.2 m². Now find the area of the shaded circle using the formula: $\pi 6.25^{2}$ . This is also 3.14*39.0625. Multiply to get 122.65625. Round to the nearest tenth: 122.7. Subtract 122.7 - 19.2 to get 103.5 m².
