For the first problem, the triangle is equilateral. This means that all three sides will have the same length. So you need to find a value for x that makes all three of those statements equivalent. I believe you could find it using a system of equations... but it’s been a while so don’t quote me on that.

For the second, ce and de are equal. Set them equal to each other and solve for x. Then plug that x value back into the side lengths.

Vesnalui [34]

$(5a-b)(5a+8b)=(5a*5a)+(5a*8b)+(-b*5a)+(-b*8b)=$ $25a^2+40ab-5ab-8b^2=25a^2+25ab-8b^2$

Find The value of x, y and z

Ratling [72]

Answer:

x = 18 ; y = 10 ; z = 102°

Step-by-step explanation:

The triangle in the pic is an isosceles triangle.

As it is an isosceles triangle , it's two sides will be equal .

$= > 3x - 42 = 12$

$= > 3x = 42 + 12 = 54$

$= > x = \frac{54}{3} = 18$

Also, both the base angles will be equal.

$4y - 1 = 39$

$= > 4y = 39 + 1 = 40$

$= > y = \frac{40}{4} = 10$

According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,

$z + 39 + 39 = 180$

$= > z + 78 = 180$

$= > z = 180 - 78 = 102$

What is the second step when evaluating the expression 49 + 63 ÷ (3 + 2 × 2) – 7? 63 ÷ 3 63 ÷ 7 2 × 2 3 + 4

Zarrin [17]

ANSWER: Multiply and Divide from left to right

To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
