To answer this, we need to use the rules of geometric shapes. An equilateral triangle is equiangular, meaning all its angle measures are equal. Since all triangles' angles add up to 180°, simply divide 180 by three to find the angle measure of each angle:

Therefore, the measure of the triangle's angle is
60°Next, we know that a characteristic of a rectangle is that each angle must be a right angle, or an angle with a measure of
90°.
Now, all we have to do is use the sum of all the angle measures to figure out the missing piece:

The missing angle measure, angle
x, equals 18°.
Hope this helps!

Answer:
115.60
Step-by-step explanation:
for a tip 85x 0.30=25.50
tax 85x0.06=5.10
total extra money 5.10+25.50=30.60
total money payed 85+30.60=115.60

Line DQ is equal to 7. Since point Q is the centeriod, this means that line DQ will equal the same as line QD. Thus, line QD is 7 making like DQ 7 as well. Hope that helped :))
