Answer:
m<1 = 87°
m<2 = 45°
m<3 = 45°
m<4 = 52°
Step-by-step explanation:
Angle C is a right angle. Therefore, it is 90°. Because line segment BC bisects angle C, the two angles would be 45° since 90 ÷ 2 = 45.
So, angles 2 and 3 equal 45°.
Now that we have two angle measures, we can find the measure of the third angle.
45 + 48 = 93°
180 - 93 = 87°
Angle 1 equals 87°.
45 + 83 = 128°
180 - 128 = 52°
Angle 4 equals 52°.
Hope that helps.
Answer:2.5
Step-by-step explanation:
Answer: -35/44
Step-by-step explanation: To multiply these two fractions together, simply multiply across the numerators and multiply across the denominators and remember a negative times a positive is a negative.
So our answer is -105/132.
To reduce our fraction divide both top and bottom by 3 to get -35/44.

Trigonometric Identities.
To solve this problem, we need to keep in mind the following:
* The tangent function is negative in the quadrant II
* The cosine (and therefore the secant) function is negative in the quadrant II
* The tangent and the secant of any angle are related by the equation:
We are given:
And θ lies in the quadrant Ii.
Substituting in the identity:
Taking the square root and writing the negative sign for the secant:
