A right triangle has only one 90° angle. Both of its other angles have measures greater than 0° and less than 90°. Why is it useful to define the tangent of 90° to equal 1, and the tangent of 0° to equal O?

*use the picture to answer the three missing parts*

Complementary angles are very close to 0° and 90°/0°. (Which)

The tangent of the small angle is very close to 1/1 or 0/1. (Which)

The tangent of the larger angle will be very close to 0/1 or 1/1. (Which)

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

step-by-step explanation:

do 6-10=

if u need it to be negative.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
