Step-by-step explanation:

As we can see, this triangle has 2 equal sides in length, which makes it an isosceles triangle. As the Base Angles Theorem states, the base angles of an isosceles triangle are congruent. In this case, angles a and b are the base angles. We now know they are both congruent, so we'll mark them both as a. Next, we notice that the measure of the other angle is 122°. We also know that the sum of all of the angle measures in a triangle is 180°. Using algebra and what we know so far, we can write this equation:

122°+a+a=180°.

When we solve for a, we get:

122°+2a=180° (add a and a)

2a=58° (subtract 122 from both sides)

a=29°

Since we know a=b, b=29°.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
