Because G is a 90 degree angle ( right angle) the 2 angles given when added together also need to equal 90 degrees:
4x + 5x = 90
Combine like terms:
9x = 90
Divide both sides by 9:
X = 90/9
X = 10
2x and 8X are supplementary angles and need to equal 180 degrees when added together:
2x + 8x = 180
Combine like terms:
10x = 180
Divide both sides by 10:
X = 180 /10
X = 18
The inside angle where they have 32 is a vertical angle to 32 so it is also 32.
The four inside angles need to equal 360 degrees.
Subtract the 3 known angles from 360 to find x:
X = 360 - 158 - 148 - 32 = 22 degree.
Answer:
<u>The correct answer is A. 12 minutes.</u>
Step-by-step explanation:
Let's solve for y, when x = 12, as follows:
y = 175 - 15x
y = 175 - 15 * 12
y = 175 - 180
y = - 5
This result means that after 12 minutes the fish tank would be completely drained and if it's needed 5 additional gallons of water could also be drained. It's not necessary to continue making more calculation with the the other options given because this is the right answer.
<u>The correct answer is A. 12 minutes.</u>
Answer:
It is impossible to draw two different triangles with these criteria.
Step-by-step explanation:
The 3,4,5 triangle is a Pythagorean triplet, but if it was said to be 6,8,10, then yes two different triangles can be made, same with any other multiple of a 3,4,5 right triangle. The 3,4,5 triangle is in its reduced form causing there to be no other triangles that can be made that still function as a triangle through the theorem of triangles where the hypotenuse has to be bigger than either side length.
Answer: tThe total dinner bill with tip = $177.90
Step-by-step explanation:
Given: Dinner bill = $148.25
Tip percent = 20%= 0.20
Total dinner bill = Dinner bill + Tip percent × (Dinner bill)
Total dinner bill = $ (148.25+0.20×148.25)
Total dinner bill = $ (148.25(1.20))
Total dinner bill = $177.90
Hence, the total dinner bill with tip = $177.90
