Answer:
x = 5
Step-by-step explanation:
The interior angles of a triangle <em>always</em> have to add up to 180 degrees.
This means you can form an equation with the three angles you have:
(10x - 4) + (8x + 3) + 91 = 180
Then, solve:
combine like terms
subtract 90 from both sides
divide both sides by 18
Answer:
Option (d) is correct.
6 + 9 + 12 +15 =
Step-by-step explanation:
Consider the given series expansion 6 + 9 + 12 +15.
since we have to write in series form of 3.
We first write each term of given series in term of 3k or 3k+3
6 can be written as 3(2) or 3(1)+3
9 can be written as 3(3) or 3(2)+3
12 can be written as 3(4) or 3(3)+3
15 can be written as 3(5) or 3(4)+3
Thus, we can write the given series as ,
or
Since, we have options to choose.
From the given option (d) matches our result.
So, 6 + 9 + 12 +15 =
The answer would b be d 8 I think
1/4 - 1/2 = -1/4 but 1/2 - 1/4 = 1/4
