Find the measure of Angle 8. measure of angle 7 = 2x+15 measure of angle 8 = 3x

aleksandrvk [35]

I do not understand the context of your question, you need extra information to find this out like a picture or a word problem.
If the angles equal each other you would have to solve for x when angle 7 and 8 equal each other. SO... based on that, x would equal 15. This means measure of angle 7 would equal 45 and measure of angle 8 would equal 45. This may not be true because I have no idea what you are asking

Which expression is a difference of squares with a factor of 5x − 8?

Olegator [25]

Answer:

$25x^2-64$

Step-by-step explanation:

Remember that the formula for the difference of squares is $a^2-b^2=(a+b)(a-b)$ . The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:
