Answer:
66
Step-by-step explanation:
Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.
So angle 2 is 57.
Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:
57+57+angle 1=180
114+ angle 1=180
angle 1= 66
Answer:
(x-4) (x-5)
Step-by-step explanation:
x^2 -9x+20
What two number multiply to 20 and add to -9
-4*-5 = 20
-4+-5 = -9
(x-4) (x-5)
Here are examples which will explain:
5 x 10= 50 therefore what we did here was 5.0 and we just moved the decimal to the right by making it a bigger number because it is multiplication
6x100= 600, here we also moved the decimal to the right 2 times because there are 2 zeros
7x 1000= 7000 we moved the decimal 3 times to the right because it has 3 zeros
Now for division
If we do 5 divided by 10 that would be 0.5 because there is one 0 and that means we move the decimal to the left once.
6 divided by 100= 0.06 we moved the decimal to the left 2 times because there are 2 zeros so basically in conclusion we do the same thing in division and multiplication with 10,100,1000,10000 but we just move the decimal to the left in division and move decimal to the right in multiplication.
Hope that helps!
Answer:
a = 12, b = 2, c = 11
Step-by-step explanation:
Simplify the left side
Numerator simplifies: (x^5yz^4)(x^5yz^4)(x^5yz^4) goes to x^15y^3z^12
Take the new numerator and simplify with the denominator:
x^15y^3z^12/x^3yz goes to x^12y^2z^11
That means a = 12, b= 2, c = 11
