Answer: Option B (2x=28°, x=14°)
Step-by-step explanation: 2x+44° = 72°
<u><em>Let the point of intersection be O</em></u>
∠O = 180° - (28°+44°)
180°-72° = 108°
∴ As we know that 2x+44=72°
2x= 72-44
2x=28°
∴x=28/2 = 14°
Therefore the correct answer is Option B (2x=28°, x=14°)
Answer:
x= 2
Step-by-step explanation:
Given that,
AB = 7.5x
BC = 6x+3
AC = 10x-5
ΔABC is an equilateral triangle.For an equilateral triangle, all sides are equal. ATQ,
AC = BC = AB
10x-5 = 6x+3
Taking like terms together
10x-6x = 5+3
4x = 8
x = 2
Hence, the value of x is equal to 2.
Answer: 226.9 square in.
Step-by-step explanation: Remember that the formula for the area of a circle is (pi)r^2. Since the diameter is 17, you divide that by 2 to get your radius: 8.5. Now, put it into the formula to get your answer. (226.865 is the original, 226.9 is rounded to tenths)
