A triangle has three angles, z1, z2, and Z3. if Z1 = 34o and Z2 = 86o, what is the measure of Z3​

60

Step-by-step explanation:

Triangle Angle Theorem

In any triangle, the sum of all angles equals 180

180 - 34 + 86

=  60

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
