The correct answer is
°.
To solve for
, you can start by finding the measures of the triangle's interior angles. Knowing that a straight line measures
°, you can subtract the given values from
° to find the measures of the respective supplementary interior angles. That would give you
°
and
°
.
Now, knowing that the measure of all the interior angles of a triangle is also
°, you can add the two interior angles you know
and subtract those from
°. Doing so would give you the measure of the missing third angle, which is
°.
Finally, because angle
is the supplementary angle of the missing angle from the previous step, simply subtract that angle's measure from
° to find
°, which is
or
°.

Step-by-step explanation:
2 gallons 25% of 4 is 1 so there is about 1 gallon of pure in there no so adding two will make 3 gallons of antifreeze bringing total to 6 gallons 3/6 = .5 boom bam 50%
The sum of the first four terms of the sequence is 22.
In this question,
The formula of sum of linear sequence is
The sum of the first ten terms of a linear sequence is 145
⇒ 
⇒ 145 = 5 (2a+9d)
⇒ 
⇒ 29 = 2a + 9d ------- (1)
The sum of the next ten term is 445, so the sum of first twenty terms is
⇒ 145 + 445
⇒ 
⇒ 590 = 10 (2a + 19d)
⇒ 
⇒ 59 = 2a + 19d -------- (2)
Now subtract (2) from (1),
⇒ 30 = 10d
⇒ d = 
⇒ d = 3
Substitute d in (1), we get
⇒ 29 = 2a + 9(3)
⇒ 29 = 2a + 27
⇒ 29 - 27 = 2a
⇒ 2 = 2a
⇒ a = 
⇒ a = 1
Thus, sum of first four terms is
⇒ 
⇒ 
⇒ S₄ = 2(2+9)
⇒ S₄ = 2(11)
⇒ S₄ = 22.
Hence we can conclude that the sum of the first four terms of the sequence is 22.
