In order to determine the value of x, consider that one of the interior angles of the triangle is given by:
180 - (4x - 18)
= 180 - 4x + 18
= 198 - 4x
Next, consider that the sum of the interioir angles of a triangle is equal to 180:
(2x + 6) + 36 + (198 - 4x)
= 2x + 6 + 36 + 198 - 4x
= -2x + 240
this is equal to 180:
-2x + 240 = 180
-2x = 180 - 240
-2x = -60
x = 60/2
x = 30
Hence, the value of x is x = 30
Answer:
Step-by-step explanation:
The standard form formula for a circle equation is 
, where (h,k) represents the center of the circle, and r represents the radius.
r=10
(h,k)= (9,3)
Answer:
2sqrt(13)
Step-by-step explanation:
x = sqrt(36 + 16)
x = sqrt(52)
x = sqrt(4*13) = 2sqrt(13)
Answer:
Step-by-step explanation:
you add two fractions:
3/5+1/3=
find the common denominator = it is 15 (3*5)
9/15+5/15=14/15
Answer:1/10
Step-by-step explanation:
To convert a ratio to a fraction, you divide the number on the left by the number on the right. This gets you (3/5)/6. When dividing fractions by whole numbers, you need to convert the whole number to a fraction. I converted 6 to 6/1, so that gave me (3/5)/(6/1). You then multiply the top number by the bottom number to get the numerator of the answer, and the middle 2 numbers multiplied is the denominator. The answer is (3x1)/(5x6), or 3/30, which can be simplified to 1/10.
