Answer:
∠1 = 90°
Step-by-step explanation:
The angle inscribed in a semicircle is always 90°
∠1 = 90°
Answer:
=10383435
Step-by-step explanation:
Answer: 1/5 or 0.2
Step-by-step explanation: each number is just dividing by 5
like 625/5 = 125
125/5 = 25
25/5 =5
5/5 = 1
similarly 1/5 = 0.2 or 20%
I’m guessing that x is the angle on the right that isn’t shown?
Anyways if that’s the case then:
We know that the sum of all the angles of a triangle add up to 180 degrees.
In this triangle we know that one angle is 55 degrees and the other is 90 degrees, so to find the last angle we do the sum of all the angles and we remove the 2 angles:
180- (55+90)= 35 degrees.
x= 35 degrees
Picturing the tent helps, but we can actually solve this question using simple algebra and no knowledge of triangles.
The key is this function:
(b/h) = 2/√3
We want to get h by itself. First, multiply both sides by h:
b = h(2/√3) Now multiply both sides by the reciprical, (√3/2)
(√3/2) b = h
Therefore, the answer is C) h= b(√3/2)
