Can someone help me really please

Mathematics
1 answer:
JulsSmile [24]2 years ago

Answer:

26

Step-by-step explanation:

Let x represent the missing number

8\frac{11}{15} = 7\frac{x}{15}

Convert both fractions to improper fractions

\frac{131}{15} = \frac{105 + x}{15}

Cross multiply

15(105 + x) = 15(131)

1,575 + 15x = 1,965

Subtract both sides by 1,575

15x = 1,965 - 1,575

15x = 390

Divide both sides by 15

x = \frac{390}{15}

x = 26

What is mZDAR in circle A?
Andreas93 [3]

Answer:

68°

Step-by-step explanation:

Since, angle subtended on the circumference of the circle is half angle subtended on the center of the circle.

\therefore m\angle DBR = \frac{1}{2} \times m\angle DAR\\\\\therefore 34\degree = \frac{1}{2} \times m\angle DAR\\\\\therefore 34\degree \times 2= m\angle DAR\\\\\therefore 68\degree = m\angle DAR\\\\\therefore m\angle DAR=68\degree
