I think this is going to help you understand the concept and hope that the answer is correct. Thanks for understanding.
Answer:
45°, 225°
Step-by-step explanation:
Given that;
Tan x = 1
We can get Tan⁻¹ of 1
x = Tan⁻¹ 1
x = 45
45° is the acute angle in the first quadrant
Tangent is positive in the 1st, and the 3rd quadrant.
Therefore in the third quadrant, x = 180 + 45 = 225
Hence; x = 45° or 225°
A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.
This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.
x + x + 40 = 180
2x + 40 = 180
2x = 140
x = 70
The base angles measure 70 deg.

I don't see it simplifying further, there are other ways that can change it to
, but that won't really be that simplified per se.
