Answer:
22 and 158
Step-by-step explanation:
Supplementary angles add to 180. This is means there is a small and large angle. Adding together, they make 180.
- "the larger angle measures four degrees more than seven times the measure of a smaller angle" is represented as 7x+4.
- "x represents the measure of the smaller angle" is represented as x.
x + 7x+4 =180
8x+4=180
8x=176
x= 22
This is the measure of the smaller angle. The larger angle is 7(22)+4 = 158
1. it is right-angled triangle because it has a 90 degree angle.
<h3>The present age of Jackson is 25 years old</h3>
<em><u>Solution:</u></em>
Let the present age of Jackson be "x"
Therefore
Jackson's age 7 years ago = x - 7
And, Jackson's age after 20 years = x + 20
From given question,
Jackson’s age was 2/5 of the age he will be 20 years from now 7 years ago
Thus present age of Jackson is 25 years old
Given that, 
= 39
We will find the second term 
Similarly,
Now we use the option checking method,
Suppose we check 4th option
a_{n}= 6n + 33
for n=1
= 6(1) + 33 = 39
It means option D is correct
X² <span>+ 11x = -28
to find the solution of this polynomial, it'll be easiest to try and factor it. the first thing you need to do is move everything to one side:
</span>x² + 11x = -28 ... add 28
x² + 11x + 28 = 0 ... factor
(x + 7)(x + 4) = 0 ... now set both of your factors equal to zero and solve for x
x + 7 = 0
x = -7
x + 4 = 0
x = -4
