Find the value of x.

Mathematics
1 answer:
Deffense [45]2 years ago
6 0

Answer:

Step-by-step explanation:

the funny lines in the corners of the triangle mean that the angles are the same.  Maybe you knew that?

The supplementary angle at the top right is just

180- 17x -23

now you have expressions for each of the 3 angles of the triangle which all add up to 180°

180= 7x + 2  +  7x +2   +  180- (17x -23)

180 = 14x +4 + 180 - 17x +23

180 = -3x +207

3x = 27

x = 9

Tanya wants to find the height of the tree. She walks away from the base of the tree so the tip of her shadow coincides with the
Vikki [24]
<span><u>Answer </u>
18 feet and 4.5 inches

<u>Explanation </u>
You are going to use the concept of similar triangle.
∆CED≡∆CBA
This is because they share the angle at C and also they both have an angle of 90o.
Let EC = X, then BE = 2.5X. So, BE = (X + 2.5X) = 3.5X
The scale factor EC/BC=x/3.5x=2/7
EC/BC=ED/BA=2/7
BA=7/2×63 in
The height of the tree = 220.5 inches. This is equal 18 feet and 4.5 inches.

Which equation in slope intercept represents the line that goes through the points (-1, 6) and (1, -2)
Afina-wow [57]

Answer:

D) y=-4x+2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-2-6)/(1-(-1))

m=-8/(1+1)

m=-8/2

m=-4

y-y1=m(x-x1)

y-6=-4(x-(-1))

y-6=-4(x+1)

y=-4x-4+6

y=-4x+2
