Korolek [52]

Answer:

Step-by-step explanation:

sin²β + sin²β×tan²β = tan²β

sin²β( 1 + tan²β ) = tan²β

~~~~~~~~~~~~~~~~

<u><em>sin²β + cos²β = 1  </em></u>

<u><em /></u>\frac{sin^2\beta }{cos^2\beta } + \frac{cos^2\beta }{cos^2\beta } = \frac{1}{cos^2\beta } ⇒ tan²β + 1 = sec²β ⇔ 1 + tan²β = sec²β

~~~~~~~~~~~~~~

1 + tan²β = \frac{1}{cos^2 \beta }

L.H. = sin²β ( \frac{1}{cos^2 \beta } ) = tan²β

R.H. = tan²β

Use the figure to find the measure of angle 1. *
QveST [7]

Answer:  angle 1 = 110 degrees

This is because angle 1 and the red 110 degree angle are corresponding angles.

They correspond to one another due to the fact they are both in the southwest corner of each 4-corner angle configuration (which is the result of crossing two lines)

Corresponding angles are congruent only when we have parallel lines like this.
