A number that is less than 85, the number has 26 and 6 as factors is, 78
Something that you should remember is that the sum of the angles of a triangle add up to 180°.
Since we are given 100° and that the other two angles are equal, we can set up an equation like this:
, where x is the 2 angles.
Doing the math, the measure of each unknown angles is 40°.
Answer:
14.13 units^2.
Step-by-step explanation:
The area of a circle is found by doing pi * r^2. In this case, the diameter is 6. 6 / 2 = 3. So, r = 3.
pi * 3^2 = pi * 9 = 9pi.
This is a semicircle, so the area will be half of the whole circle.
9pi / 2 = 4.5 * pi = 4.5 * 3.14 = 14.13 units^2.
Hope this helps!
