Answer:
108
Step-by-step explanation:
"five times a number x, decreased by 2" can be expressed as: 5x - 2
Now,
5x - 2 = 5*22 - 2 = 110 - 2 = 108
Answer:
Like the angles BAC (56°) and BDC has the same arc BC in the circumference, these angles must be congruent, then angle BDC must be equal to 56°.
Answer:6.928
Step-by-step explanation: formula A=√ 3*(side^2/4)
The perimeter of equilateral triangle DEF is 24 cm.
<h3>
Triangle</h3>
A triangle is a polygon with three sides and three angles. Types of triangles are<em> equilateral, isosceles, obtuse, scalene</em>.
Given that triangle ABC is equilateral, also triangle DEF is equilateral.
DE = DF = EF = 10 - 1 - 1 = 8 cm
Perimeter of DEF = 8 + 8 + 8 = 24 cm
The perimeter of equilateral triangle DEF is 24 cm.

In general, for these kinds of problems, repeatedly subtract 360 degrees until you get something that lies between 0 and 360 degrees, since two coterminal angles will always differ by some multiple of 360 degrees.
In this case, our desired angle is 495-360=135 degrees.
