Since they are both degrees of an angle they would be equal:

3x+80 = 7x-40

80 = 4x-40

120 = 4x

x = 120/4 = 30 degrees

7x-40 represents the central angle, the arc 3x+80 equals the central angle, it is the same, so 7x-40=3x+80. 7x-3x=80+40. 4x=120. X=30. Let’s plug it in. This can be a way to check the answer. We get: angle=170 and arc=170. So x=30 is correct.

A rectangular prism has a height of 4 meters, a surface area of 96 square meters, and a base area of 8 square meters. Calculate
tatyana61 [14]
The perimeter is 56m

H = 4m
Base area =  96m^2

96/4 = 24
Therefore the length is 24m

4m + 24 = 28m
multiplied by 2 is equal to 56m.

3. Given ABCD ≅ FGHJ and mC = 9x - 7, mH = 5x + 13, find the value of x and the measures of angle C and angle H. Show all work
Bas_tet [7]
Since congruence and similarity for polygons is posted in a specific order, we know that angle A=angle F, side A=side F, die B=side G, and so on. Therefore, we have that angle C=angle H = 9x-7=5x+13. Subtracting 5x from both sides to separate the x using the subtraction property of equality, we get 4x-7=13. Next, we can add 7 to both sides to get 4x=20, and divide both sides by 4 to isolate the x and get x=5. Plugging that into angle C or angle H, we get that 9x-7=9*5-7=45-7=38=5*5+13.
