I think it would be a 70 degree angle since a 90 degree is a right angle and subtracting from the 20 it would 70 so yep if this is wrong I am sorry.
Answer:
y = 8(x + 2)^2 + -15
Step-by-step explanation:
Factor out the leading coefficient.
y = 8(x2 + 4x) + 17
Form a perfect-square trinomial.
y = 8(x2 + 4x + 4) + 17 + -32
Write in vertex form.
y = 8(x + 2)^2 + -15
Answer: Hope this helps, I think I did the right math if not I'm sorry

<h3>What is addition?</h3>
The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
a.
Andy = £9500
Bevan = £25000
Cheryl = £11250
Elliott = £12750
Frankie = £29500
Grace = £11000
Deva = £72000
Total Income = £166,000
To get the mean Income, we will divide the total income by 6 which is the number of people.
= £166,000/7
= £23714.28
b. If Deva's income is excluded, there'll be 6 people left.
Total income = £99000
Mean income = £99,000/6
= £16,500
a) The mean income to 2 DP is £23714.28. b. If Deva's income is excluded, then the mean income will be £16,500.
