In Exercises 3 and 4, find the values of x and y <br> plz help!!!

Answer:

x = 20°

y = 30

Step-by-step explanation:

The triangle given on close inspection, it is an equilateral triangle.

Each angle in an equilateral triangle is equal. Likewise, each side is equal.

Thus;

16 + y = 46

y = 46 - 16

y = 30

The triangle that has angle 80°, the other complete angle is 60° because it's an angle of an equilateral triangle.

Thus, the smaller angle there is;

180 - (80 + 60) = 40°

Because sum of angles in a triangle is 180°

Now, x + 40 = 60°

Since that's also an angle of an equilateral triangle.

x = 60 - 40

x = 20°

Multiply (7x – 6)(8x +3). A. 56x 2 – 27x – 18 B. 12x 2 – 50x + 8 C. 56x 2 – 18 D. 56x 2 – 69x + 18

(7x-6)(8x+3)

Use the FOIL method

F: 7x • 8x = 56x^2
O: 7x • 3 = 21x
I: -6 • 8x = -48x
L: -6 • 3 = -18

$56x^{2}+21x-48x-18$

Simplify
$56x^{2}-27x-18$

Your answer is A.
