Answer:
see the explanation
Step-by-step explanation:
we know that
An equilateral triangle has three equal sides and three equal interior angles.
The measure of each interior angle is 60 degree
see the attached figure to better understand the problem
Let
b ----> the length side of the triangle
In the right triangle ABD
----> by SOH (opposite side divided by the hypotenuse)
substitute the given values
solve for b
Remember that
substitute
simplify
5/2 = 5:2
Lets take 5:2 as 5x and 2x.
5x + 2x = 140
7x = 140
x = 140/7
x = 20
So, 5x = 5x20 = 100 red bricks
and, 2x = 2x20 = 40 grey bricks.
100 + 40 = 140 bricks
So, to build the decorative wall, 100 red bricks and 40 grey bricks were used.
Answer:
990 feet
Step-by-step explanation:
Fabricator 4 recieved what's left after the rest were distributed
= 5,840 - 2,500 - 1,200 - 1,150 = 990
the set of all values that a function will return as outputs
Answer:
B
Step-by-step explanation:
540 is the sum of all angles in a pentagon
The ANGLE STP is 180-50 = 130
540 - 130 is 410
