Answer:
14.125
Step-by-step explanation:
You combine the two equations and get
8x - 23
and since they're in a 90 degree angle you do
8x - 23 = 90
add 23 to both sides
8x =113
divide 113 by 8 and you get 14.125 and if you plug it in for both x's you get 24.625 + 65.375 you get an even 90
Answer:
84 sq.m.
Step-by-step explanation:
Given : Sides of triangle are 13 cm,14 cm and 15 CM
To Find :find the area of the triangle
Solution:
We will use heron's formula :
Where
a = 13
b = 14
c = 15
Hence the area of the triangle is 84 sq.m.
Tip: use Heron's formula
Answer:
The slope of one of the guy wires is m=0.7
Step-by-step explanation:
Divide the vertical distance of the guy wire by the horizontal distance of the guy wire to find the slope of one of the guy wire.
We have
d = 100ft ----- horizontal distance
h = 70ft ------- vertical distance
Then,
m = h/d
Put the values in the given formula:
m = 70/100
m = 0.7
Thus the slope of one of the guy wires is m=0.7
