Answer:
d. m∠Q = 75 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180°. This triangle is marked to show it is an isosceles triangle, so the two base angles have the same measure.
∠P +∠Q +∠R = 180°
x° +(2x +15)° +(2x +15)° = 180°
5x = 150 . . . . . . . . . . . . . . . . . . . divide by °, subtract 30
x = 30 . . . . . . . . . . . . . . . . divide by 5
m∠Q = (2x +15)° = (2(30) +15)°
m∠Q = 75°
Answer:
Dilation
Step-by-step explanation:
A dilation changes the size of a figure by enlarging the figure of making the figure smaller. The sides will be proportional and the angles will be congruent making the figures similar.
$85.20/6= $14.20/pair is the answer because unit price equals cost/pairs
Answer:
27.
Step-by-step explanation:
It is one property of exponents that for any numbers <em>a, b,</em> and c
Therefore, using this property the expression 
becomes
.
and when when simplify the exponents, we get:
.
Since for any number 
<em>( </em>
<em> in the exponent means the square root) , </em>
is rewritten as
which simplifies to
Thus,
