This uses the properties of a 30-60-90 triangle. the 90 m is opposite the 60 degree angle to convert to the side opposite the 30 divide 90 by
90 /
= 51.96 m or B
Answer:
∆<em>LMN</em> ~ ∆<em>LQR</em>
Step-by-step explanation:
All you have to do is match their similar corresponding angles.
* These are congruent by the Angle-Angle Similarity Postulate, where at least two angles of both triangles are congruent, which in this case is ∠<em>L</em> [Vertical Angles Theorem] and ∠<em>Q</em> & ∠<em>M</em>. This obviously gives us our third side in each triangle, which must sum up to 180° altogether, therefore you have your answer.

Answer:
1:0.06
Step-by-step explanation:
since there is a 6% sales tax, which is the same as 0.06. to calculate your tax, you would multiply both of the sides of the ratio by 75, and the left side will show you subtotal of what you are buying, the right will show tax.
Equation parallel to y = -x is y=-x+k
so 4.5 = -7 + k so k - 11.5
Equation is y = -x + 11.5
