Answer:

1 = 115°

2 = 115°

3 = 65°

Step-by-step explanation:

P=65, so S (3) =65

360-65-65=230

230/2=115

Q (1) = 115

R (2) = 115

Answer:  <1=115°, <2=115°, <3=65°

Step-by-step explanation:

Since one of the properties of isoceles trapezoids are the fact that they have congruent lower base angles, we can assume that <3=65°. Since each quadrilateral contains angles that add up to 360°, Since we have 2 angles that are both 65°, we can add them together, which results in 130°, and subtract from 360°, which results in 230°. Since isoceles trapezoids have equal upper base angles, we can divide this by 2, which results in angles <1 and <2 being 115°.

Tell whether each equation has one, zero, or infinitely many solutions.<br>5(x - 3) +6= 5x - 9​
ollegr [7]

5(x - 3) +6 = 5x - 9​ has infinitely many solutions

<h3><u>Solution:</u></h3>

Given equation is 5(x - 3) +6 = 5x - 9​

We have to find whether the given equation has one, zero, or infinitely many solutions

Let us solve the given equation

5(x - 3) + 6 = 5x - 9​

Let us use BODMAS rule to solve the given equation

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right

So let us first solve for brackets in given equation

5x - 15 + 6 = 5x - 9

5x - 9 = 5x - 9

0 = 0

Since the statement is true, there are infinitely many solutions

Answer:

y = 2/3x

Step-by-step explanation:

So we know, when lines are perpendicular that they share the same slope. The slope in the equation of y = 2/3x + 7 is 2/3x. So, we have our slope. Now, we just need to find our b. We plug in the point that you gave us into the equation y = mx + b.

3 = 2/3(2) + b

we multiply the denominator 3 by 2, then divide that by the numerator 2.

3 = 3 + b

subtract 3 from itself and from the opposite side of the equal side 3.

0 = b

in the end, there is no b for this equation. Our answer is

y = 2/3x
