Answer: 103 degrees
Step-by-step explanation: all angle of a regular triangle always add up to 180. so 62+15=77. and 180 - 77= 103
Answer:
Posts: 34
Area: 264 yard²
Step-by-step explanation:
Posts: (7 x 2) + (10 x 2) = 34
Area: 2 x (7 - 1) x 2 x (12 - 1) = 2 x 6 x 2 x 11 = 264 yard²
Answer:
a. Let x = hours surfing and let y = hours lifting weights
b. x + y = 6
c. 100x + 75y = 500
Gradient is basically the same as slope in this instance. so the answer would be positive 4.
Answer:
2. 40.83 or 13π
3. a) 6π/5
b)21.6π
Step-by-step explanation:
2. Use the proportion arc length over angle measure:
x/360 = 7.94/70
x = 360 * .113 = 40.83 or 13π in exact form
3. a) 24π/20 because circumference divided by the total number of slices which reduces to 6π/5
b) 360/20 = 18 degrees per slice, so 13 slices have an angle measure 234 degrees
Set up a proportion between the area of the full pizza over the angle measure and the area of the pizza (the unknown value being solved) and its angle measure
144π/360 = x/234
(234*144π)/360 = 21.6π
