Since an isosceles triangle has two angles that are the same, and one different, the 120 degrees would be the different one. 180-120= 60 degrees 60/2=30 degrees
Answer:
the answer would 12
Step-by-step explanation:
Answer:
I think that the volume of sphere is the first one
(A) Find the value of x. Round to the nearest tenth of a degree<span>
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft
In order to get the angle formed between the ground and the foot of the plank,
cos (theta) = ground / plank
cos (theta) = 9 / 41
</span><span>cos (theta) = 0.21951...
</span>theta = cos^-1(<span>0.21951...)
</span><span>theta = 77.3 degrees
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
</span><span>Height = square root (1600)
</span><span>Height = 40
(A) 77.1 Degrees
(B) 40 feet</span>
Answer:
The 1st option
Step-by-step explanation:
Remember BPEMDAS
B - Brackets
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
She has to first multiply and distribute first, not add. Adding comes last.
