Answer:

Step-by-step explanation:

1) ∠1 + 33 = 180 {Straight line}

∠1 = 180 - 33

∠1 = 147

2){Exterior angle of a triangle equals the sum of opposite interior angles}

∠2 = 47 + 33

∠2 = 80

3) ∠2 +x = 180 {straight line}

80 + x = 180

x = 180 - 80

x = 100

{Exterior angle of a triangle equals the sum of opposite interior angles}

∠3 = 100 + 48

∠3 = 148

PLEASE HELP How can the area of this triangle be determined by forming a rectangle? Select from the drop-down menus to correctly

Yuri [45]

Just add a similar triangle from the opposite side

Then what happens

Hypotenuse of this triangle becomes common and diagonal of the rectangle.

Now

Length=L=5
Breadth=B=4

Area

$\\ \tt\hookrightarrow LB=5(4)=20$

Area of triangle=20/2=10units^2

8.3.5 Ana's monthly salary was $2000 in May. In June, she received a 20% raise. In July, she received a 20% pay cut. After the t

Harman [31]

Answer:

<u>After July, Ana's monthly salary was $1920</u>

Step-by-step explanation:

In May, Ana's monthly salary was $2000. During the next month, the salary increased by 20%, or (0.2)(2000)

$2000+(0.2)(2000)=2000+400=2400$

So, in June, Ana's monthly salary was $2400. During the next month, the salary decreased by 20%, or (0.2)(2000)

$2400-(0.2)(2400)=2400-480=1920$

Therefore, after the two changes, Ana's monthly salary was <u>$1920</u>

Choose the simplified form of the fifth term of 6C4(2x)2(-y2)4.

Katarina [22]

You didn't give us the choices. It doesn't matter. I think you're trying to write

$\displaystyle {6 \choose 4} (2x)^2 (-y^2)^4$

$= \dfrac{6!}{4! 2!} ( 4x^2 y^8)$

$= \dfrac{6(5)}{2} ( 4x^2 y^8)$

$=60x^2 y^8$

Answer: 60 x² y⁸

X(2x-8) = 0 how do you solve

sleet_krkn [62]

x * 2x = 3x X*-8= -8x

minus 3x on both side

= -11x

-11x = 0

divide -11 on both side

= 0
