Answer:

Step-by-step explanation:

x + 3x + 4x + 70° + 90° = 360° ( being complete turn )

8x + 160° = 360°

8x = 360° - 160°

8x = 200°

x = 25°

3x = 3 * 25°= 75°

4x = 4 * 25° = 100°

Answer:

x=20

3x= 3(20)=60

4x= 4(20)=80

Step-by-step explanation:

The angles CD is 90 degrees because the small square indicates

it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).

so AB + 70+ 90= 180 degrees

AB= 180 -70-90

AB=20

x=20

3x= 3(20)=60

4x= 4(20)=80

Question 7 of 25 Which of the binomials below is a factor of this trinomial? x - 6x-16 O A. X-1 O B. X-8 OC. X-16 O D. x-2

kvasek [131]

Answer:

(x-8) is the factor.

Step-by-step explanation:

The given trinomial is $x^{2}-6x-16$ .

We need to find the factor of this trinomial.

$x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)$

The factors of $x^{2}-6x-16$ is (x-2) and (x-8).

So, the factor of $x^{2}-6x-16$ is (x-8). Hence, the correct option is (B).

What is the length of a hypotenuse when the legs are 5 and 12

Alisiya [41]

By using pythagoras theorem where
(Base)^2 +(perpedicular)^2 = (hypotenuse)^2
So,
(5)^2 +(12)^2 = (hypotenuse)^2
25 + 144 = (hypotenuse)^2
169 = (hypotenuse)^2
13 = hypotenuse

So, hypotenuse = 13
