Step-by-step explanation:
1/2 × height × base
1/2 × 6.3 × 8
6.3 × 4 = 25.2 ans.
therefore, area of the ∆ is 25.2 ft ².
1.) 3 + 2 x 10 = 3 + 20 = 23
2.) 2(1-4)^2 = 2(-3^2) = 2(9) = 18
3.) -3^2 + 3^2 = 9 + 9 = 18
4.) 8 - [(4-7) + (8-1)] = 8 - [-3 + 7] = 8 - 4 = 4
5.) 4 - {8 - (2-4)} = 4 - {8 - (-2)} = 4 - {8 + 2} = 4 - 10 = -6
In math for we have:
2x-2=x+64
which turns into:
x=66
(subtract x from right) & (add two from left)
Answer:
Step-by-step explanation:
Quadrilaterals add up to 360 degrees.
Let the missing angle = x
68 + 52 + 125 + x = 360
245 + x = 360
Subtract 245 from both sides.
245 - 245 + x = 360 - 245
Combine
x = 115
