An isosceles triangle. This triangle has 2 sides that are equal.
The complementary angels are the two angles that sum 90°.
- complementary (27° and 63°) or (26 and 64°)
- three angels that sum 180°
(68°+42°+70° = 180°)
hope this helps :)
Commercial jet's speed = 2x-162 (plug this in the equation below)
Private jet's speed = x
Equation:
10(x) = 8(2x-162)
10x = 16x - 1296
6x = 1296
x = 216 (Private jet's speed)
Take the first equation and plug x value in;
2x-162
2(216) - 162 = 270 ( Commercial jet's speed)
If it has x intercepts at r1,r2,r3 then the factored form is
f(x)=a(x-r1)(x-r2)(x-r3)
where a is a constant not equal to 0
so
intercepts of -2,0, 1
f(x)=a(x-(-2))(x-0)(x-1)
f(x)=a(x+2)(x)(x-1)
passes through the point (2,16)
find a buy subsituting the point (2,16) into it
16=a(2+2)(2)(2-1)
16=a(4)(2)(1)
16=8a
2=a
the function is
f(x)=2(x+2)(x)(x-1)
Edited answer: 97 girls didn't have brown eyes
Work Shown: 136 girls in total, then subtract that by how many girls did have brown eyes. And you get the equation 136-39= which equals to 97 girls.
