This would be SAS. If that’s wrong I’m sorry but it’s the only thing that makes sense, the dashes indicate they are the same and then the circle at the point also indicates that they’re the same so you have two sides and one angle that are the same, so it should be SAS.

Does the point (6,3) satisfy the equation y = 4(x – 5)?

Darina [25.2K]

Answer:

Step-by-step explanation:

plug (6,3) into the given equation to find out

3 = 4(6-5)

3 = 4(1)

3 = 4

since 3 does not equal 4, the point (6,3) does not satisfy the equation y=4(x-5)

E and F are complementary. If m E = 9x - 38 and mF = 2x + 40, find m F pls I need help

larisa86 [58]

Answer:

<h2>m $\angle$ F = 34°</h2>

Step-by-step explanation:

If E and F are complementary I means that the sum of their angles add up to 90° since all complementary angles have the sum of their angles equal to 90°

To find m $\angle$ F add m $\angle$ E and m $\angle$ F and equate it to 90 to find x then substitute it into the expression for m $\angle$ F

Thats

m $\angle$ E + m $\angle$ F = 90

$\rarr$ 9x - 38 + 2x + 40 = 90

$\rarr$ 11x + 2 = 90

$\rarr$ 11x = 90 - 2

$\rarr$ 11x = 88

Divide both sides by 11

x = 8

Now we have

if m $\angle$ F = 9x - 38

m $\angle$ F = 9( 8) - 38

m $\angle$ F = 72 - 38

We have the final answer as

<h3>m $\angle$ F = 34°</h3>

Hope this helps you
