Because two angles are equal, sides AB and AC will have equal lengths, and so, we can set each expression equal to each-other.
4x + 4 = 6x - 14
Subtract 4x from both sides.
4 = 2x - 14
Add 14 to both sides.
18 = 2x
Divide both sides by 2.
x = 9.
Because we have a constant value of x, we can solve for BC.
BC = 2x + 7
2(9) + 7
18 + 7
25
<h3>The value of BC is 25.</h3>
Below average, because the average car weight is 4,000 pounds, and the average miles per gallon is about 22 miles per gallon.
Answer:
5
Step-by-step explanation:
Apply the formula A^2 + B^2 = C^2
13^2 = 169
12^2 = 144
169 - 144 = 25
Square root of 25 is 5
Answer:
Length of CD is 10.7 cm
Step-by-step explanation:
we are given to find length of CD
Calculation of CD:
Firstly, we will find AC
In triangle ABC, we can use trig
now, we can find CD
In triangle ACD , we can use trig
now, we can plug AC=5
The only right triangle that has an angle with a tangent of 1 is a 45-45-90 right triangle.
