Answer:
Step-by-step explanation:
x+(4x-8)+(x+8) = 180
x = 30
∠C = x+8 = 38°
height = 7sin38°
area =0.5·13·7sin38° ≅ 28.0126 cm²
Draw a right triangle with a right angle and a 75 deg angle at the bottom.
The hypotenuse is the length of the ladder.
sin A = opp/hyp
sin 75 = 20/hyp
hyp = 20/sin 75 = 20.7
Answer: 20.7 ft
Answer:
3 ft
Step-by-step explanation:
The volume of the box is given by the formula ...
V = Bh
where B is the base area and h is the height. Solving for h, we get ...
h = V/B
Filling in the numbers gives us the height:
h = (20 1/4 ft^3)/(6 3/4 ft^2) = (81/4)·(4/27) ft = 3 ft
The height of the box is 3 feet.
If it’s a horizontal line, we focus on the y-coordinates.
(-7,5)
-7 is a x-coordinate
5 is a y-coordinate
The answer is y = 5
Answer:
UST =40.4, RST=80.8
Step-by-step explanation:
Bisects means divides in two, therefore UST is the same as RSU (40.4) all you need to do to solve for RST is multiply 40.4 by 2 which is 80.8
