Answers:

14 + 18 ÷ 2 x 18 – 7 = 169

  • 14 + 9 * 18 - 7
  • 14 + 162 - 7
  • 169

60 – 9 x 8 ÷ 8 x 6 = 6

  • 60 - 72 / 8 * 6
  • 60 + -216/4
  • 60 - 54
  • 6

15 x 10 + 12 ÷ 3 + 9 = 163

  • 150 + 12 / 3 + 9
  • 150 + 4 + 9
  • 163

(10 ÷ 5)3 + 100 – 9 x 11 = 7

  • 2 * 3 + 100 - 9 * 11
  • 6 + 100 - 99
  • 7

8 x 4 + 9 – 9 + 18 = 50

  • 32 + 9 - 9 + 18
  • 41 - 9 + 18
  • 32 + 18
  • 50

3 x 8 x 2 – 42 + 5 = 11

  • 24 * 2 - 42 + 5
  • 48 - 42 + 5
  • 11

169= (24/2)^2 +(d/2)^2
OlgaM077 [116]

Answer: d = ±10

<u>Step-by-step explanation:</u>

169 = (\frac{24}{2})^{2} + (\frac{d}{2})^{2}

169 = (12)² + \frac{d^{2}}{4}

169 = 144  + \frac{d^{2}}{4}

25 =            \frac{d^{2}}{4}

100 = d²

√100 = √d²

 ±10 = d

What is the value of x? x = 23   x = 35 x = 58 x = 93
Akimi4 [234]

we know that

m∠SQR+x=180 -------> by supplementary angles

so

m∠SQR=180-x

The sum of the internal angles of a triangle is equal to 180 degrees

m∠SQR+m∠QSR+m∠SRQ=180

substitute the values in the formula

m∠SQR+35+58=180

m∠SQR=87 degrees

<u>Find the value of x</u>

m∠SQR=180-x

x=180-m∠SQR

x=180-87

x=93 degrees

therefore

<u>the answer is</u>

the value of x is 93 degrees
