Answer:
∠ A = 66°
Step-by-step explanation:
Supplementary angles sum to 180° thus
∠ A + ∠ B = 180 , substitute values
2x - 14 + 3x - 6 = 180 , that is
5x - 20 = 180 ( add 20 to both sides )
5x = 200 ( divide both sides by 5 )
x = 40
Thus
∠ A = 2x - 14 = 2(40) - 14 = 80 - 14 = 66°
I am pretty sure it is (a) because 9 and 15 and 3 and 6 can be all divided by 3
Answer:
What is .11111111 as a fraction?
To write .11111111 as a fraction you have to write .11111111 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.11111111 = .11111111/1 = 1.1111111/10 = 11.111111/100 = 111.11111/1000 = 1111.1111/10000 = 11111.111/100000 = 111111.11/1000000 = 1111111.1/10000000 = 11111111/100000000
And finally we have:
.11111111 as a fraction equals 11111111/100000000
Step-by-step explanation:
Answer:
Answer is 1/2 or .5.
Step-by-step explanation:
Out of a die, numbers 2, 4, and 6 are even. So 3/6 numbers on a dice are even. Reduced, the answer is 1/2.
Answer:
A. 27 degrees, 63 degrees, 90 degrees.
Step-by-step explanation:
Let the angle of the triangle be x
<u>Given the following data;</u>
3 : 7 : 10 = 3x : 7x : 10x
We know that the sum of the sides of a triangle is equal to 180 degrees.
3x + 7x + 10x = 180
20x = 180
x = 180/20
x = 9
<u><em>For the first side;</em></u>
3x = 3 × 9 = 27°
<em><u>For the second side;</u></em>
7x = 7 × 9 = 63°
<em><u>For the third side;</u></em>
10x = 10 × 9 = 90°
Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.
