Step-by-step explanation:
5r+1=a(m+r)
or , 5r+1=am+ar
or, 5r-ar=am-1
or , r(5-a)=1(am-1)
: <u>r</u><u> </u> =<u>(</u><u>am-1)</u>
1 (5-a)
That is for Geometry. So Pythagorean Theorem: a2 + b2 = c2. The Pythagorean Theorem is a formula that gives a relationship between the sides of a right triangle The Pythagorean Theorem only applies to RIGHT triangles. A RIGHT triangle is a triangle with a 90 degree angle.
12=5x-13x-44
combine like terms
12 = -8x -44
add 44 to each side
12+44 = -8x
56= -8x
divide by -8 on each side
56/-8 = x
-7 =x
Answer:
45° and 12
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
(8)
The polygon has n = 8, that is 8 exterior angles, thus
exterior angle = 360° ÷ 8 = 45°
(9)
The number of sides n is
n = 360 ÷ 30 = 12
