Step-by-step explanation:
I believe it is 45°.
there are only 3 types of special right triangles.
30-60-90
45-45-90
and Pythagorean triple triangles
Step-by-step explanation:
5+4m=21
4m=21-5
4m=16
m=16/4
m=4
<span>y = -7
You cannot divide by 0. If y = -7, the denominator would be 0.</span>

Answer:
Option C. 3√3
Step-by-step explanation:
Please see attached photo for brief explanation.
In the attached photo, we obtained the following:
Opposite = a
Adjacent = 3
Hypothenus = 6
Angle θ = 60°
We can obtain the value of 'a' as follow:
Tan θ = Opposite /Adjacent
Tan 60° = a/3
Cross multiply
a = 3 x Tan 60°
But: Tan 60° = √3
a = 3 x Tan 60°
a = 3 x √3
a = 3√3
Therefore, the length of the altitude of the equilateral triangle is 3√3.
