Image of the triangle is attached
Answer:
24 cm
Step-by-step explanation:
If two triangles are similar, the corresponding sides must be in the same ratio.
From the diagram, the height of the triangle is 36cm.
But the height of triangle ABE = h,
To find the height of triangle BCD, let's subtract the height of triangle ABE from 36cm.
Therefore.
Height of BCD = 36 - h.
Since the triangles are similar and their corresponding sides have the same ratio, we have the expression:
Substituting figures, we have:
Cross multiplying, we have:
20(36-h) = 10 * h
720 - 20h = 10h
720 = 10h + 20h
720 = 30h
h = 24 cm
Therefore, the height of triangle ABE is 24cm
Area Of Circle:
=3.14 • (2.5)^2
=3.14 • 6.25
=19.625cm or 19.63
Answer:
x=4
Step-by-step explanation:
Consider the coordinate pair (4,y)
We observe that,
y can take any real values to lie on the graph of the equation.
As y really isn't a constant, we exclude it and take the equation as x=4
Answer:
BC=54, DE=27
Step-by-step explanation:
(7x-1)2=16x-10
x=4
7(4)-1=27
16(4)-10=54
So you times the -2 with the bits inside the bracket so:
-2 x t= -2t
-2 x 4 2/3 = -9 1/3
So then that makes:
-2t - 9 1/3= 9 1/2
So to get what t equals you have to get it by itself so you add the -9 1/3 to both sides of the equation to get:
-2t=18 5/6
So then you divide by -2 on both sides to get
t=-9 5/12
Which is the answer. :-D
