Answer:
Is a right triangle
Step-by-step explanation:
step 1
Find the measure of angle C
Remember that
The sum of the internal angles of a triangle must be equal to 180 degrees
so

substitute the given values


therefore
The triangle is a right triangle, because has a internal angle of 90 degrees
Answer:
x = 4.86
Step-by-step explanation:
1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
In a polynomial, each constant (regular number) has a degree of 0. For example, 8 is really 8x to the power of 0.
