Law of cosines: a2 = b2 + c2 – 2bccos(A) What is the measure of P to the nearest whole degree? 35° 52° 57° 72°
Ymorist [56]

Answer: 57°

Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.

We use law of cosine formula

QR^2 = PR^2 + PQ^2 - 2* PR * PQ * cos (P)

15^2 = 14^2 + 17^2 - 2*14 * 17 * cos(P)

225 = 196 + 289 - 476 cos(P)

225 = 485 - 476 cos (P)

Subtract 485 on both sides

-260 = -476 cos(P)

\frac{260}{476} = cos(P)

P = cos^{-1} (\frac{260}{476})

P= 56.89202

So measure of angle P is 57 degrees

42 base x +53base x = 125base x. what<br>is the value of x​
Finger [1]

Answer:

<h2>x = 7</h2>

Step-by-step explanation:

The largest number is 5. Therefore x ≥ 6.

Convert numbers from x system to decimal system:

42_x=4x+2\\\\53_x=5x+3\\\\125_x=1x^2+2x+5

Solve the equation for x:

42_x+53_x=125_x\Rightarrow4x+2+5x+3=x^2+2x+5\qquad\text{combine like terms}\\\\(4x+5x)+(2+3)=x^2+2x+5\\\\9x+5=x^2+2x+5\qquad\text{subtract 5 from both sides}\\\\9x=x^2+2x\qquad\text{subtract}\ 9x\ \text{from both sides}\\\\0=x^2-7x\\\\x^2-7x=0\qquad\text{distributive}\\\\x(x-7)=0\iff x=0\ \vee\ x-7=0\\\\x=0

A preschool teacher has 17.5 feet of yarn for her students to make necklaces to raise money for a local animal shelter each neck
Scorpion4ik [409]
17.5x12=210
210 divided by 14=15
15x2.50=37.5
37.5
17.5 is feet so you need to divide by 12 for inches which gets 210 and you need each necklace to be 14 inches so you need to divide 210 by 14 which is 15 each necklace costs 2.50 so you multiply 2.50x15
You get 37.5
