Answer:
x=40
Step-by-step explanation:
<h3> firstly
180 -110 = 70 (sumnof angle of a straight line ) </h3><h3>
180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle </h3><h3>
180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 </h3><h3>
180 -110 = 70 (sumnof angle of a straight line ) also the triangle is an isocelels triangle of which the two sides have equal angle there fore 70 +70 +x= 180 140+x=180 sum of angles of a triangle </h3><h3>

Answer:
Step-by-step explanation:
A(-6, 2), B(6,-3) and C(-6, -3)
AB² = (x₂ - x₁)² + (y₂ - y₁)²
= ( 6 -[-6])² + ( -3 -2)²
= ( 6 + 6)² + ( -3 -2)² = 12² + (-5)² = 144 + 25 =169
AB = √169 = 13 units
BC² = ( -6 -6)² + ( -3 - [-3])² = (-6-6)² + (-3 +3)²
= (-12)² + 0 = 144
BC = √144 = 12 unis
CA² = (-6 - [-6])² +(-3-2)² = (-6 + 6)² + ( -3-2)²
= 0 + (-5)² = 25
CA =√25 = 5 units
length of the hypotenuse of a right triangle = 13units
First we calculate how many ways you can choose four books from a set of eight.
We use the formula n! / [r! * (n-r)!]
8! / [4! * 4!]
= 8*7*6*5 / 4*3*2*1 = 70 ways
Then we have to calculate how many permutations can be made from 4 objects which equals 4*3*2*1 = 24
So, the TOTAL number of ways = 70 * 24 = 1,680
