If the triangle is an equilateral triangle the angles should be all 60 as (60+60+60=180) if that’s true then a congruent line from the triangle would form a 60 degree angle.
so x=60°
Answer: Option A - 8/17
Cosine is Adjacent/Hypotenuse.
So B’s adjacent measure is 8, and the hypotenuse measure is 17. Thus, 8/17 is your answer.

Answer:
Draw a right triangle and name it ABC- C is your right angle. A is the angle above C and B is the angle on the side of C. AC=12 and CB=5, you have to find AB using the Pythagorean Theorem.
Step-by-step explanation:
Using the Pythagorean Theorem you say:
AB²=AC²+CB²
AB²=12²+5²
AB²=144+25
AB²=169
AB=√169
AB= 13
Answer:
X elevated to 21/25
Step-by-step explanation:
Exponent law say you have to multiplied the exponents:
(3/5)*(7/5) =
21/25
The mistake was using sumatory instead multiplication.
