we know that
In the right triangle ABC
∠
∠
------> by complementary angles
so
Step 
Find the measure of angle B
we know that
in this problem
so
Step 
Find the measure of angle A
therefore
the answer is the option
35.5° and 54.5°
Its B because 3/10ths is a little bit more than 0.35, but way less than 0.41
I am assuming you want to solve for m in each case
8n = -3m + 1
8(-2) = -3m + 1
-16 = -3m + 1
-3m = -17
m = 
8(2) = -3m + 1
16 = -3m + 1
-3m = 15
m = -5
8(4) = -3m + 1
32 = -3m + 1
-3m = 31
m = 
In a right rectangle, we have:
For your exercice, hypotenuse=12
The exercise also inform the angle 60°, then:
Answer:the relative ages of the rocks exposed in the circle cliff area are given below.
1. older rocks are exposed in the center and younger rocks in the flanking flatirons.
2. younger rocks are exposed in the center and older rocks in the flanking flatirons.
Step-by-step explanation: this is because whenever older rocks are exposed in circle cliffs, exposure occur at the center while younger rocks will be exposed in the flanking flatirons at this time.
2. But when younger rocks are exposed in contrast to the older rocks, these younger rocks are exposed at the center while the older ones receive exposure at the flanking flatirons.
Note that both cases interchange, exposure of a particular rock occur at the center and the next category of rock receive theirs at flanking flatirons.
