Answer:

Q.1.

Sum of angles of a triangle = 180°

∠A + ∠B + ∠c = 180

(3x - 9) + (4x + 15) + 90 = 180

3x - 9 + 4x + 15 + 90 = 180

7x + 96 = 180

7x = 84

x = 12

∠A = 3x - 9 = 3(12) - 9 = 36 - 9 = 27°

∠B = 4x + 15 = 4(12) + 15 = 48 + 15 = 63°

∠A = 27°

∠B = 63°

Q.2.

$using \ pythagoras \ theorem \\x^2 = 7^2 + (7\sqrt{3} )^{2} = 49 + 49(3) = 196\\x = \sqrt{196} = 14$

$sin y = \frac{opposite}{hypotenuse} = \frac{7\sqrt{3} }{14} = \frac{\sqrt{3} }{2} \\\\y = sin^{-1} (\frac{\sqrt{3} }{2} ) = 60$

x = 14

y = 60°

A store bought a tent for $230 andmarked it up 65%. The store sells thetent with an 8% tax, what is the totalcost of the tent?

Len [333]

The cost for buying the tent is $230.

65% was increasesd for selling. Then the rate is

$\begin{gathered} 230\times\frac{65}{100}=14.95 \\ So,\text{ the marked price=230+14.95=}244.95 \end{gathered}$

The tax is 8%. So this is from the marked price.

$\begin{gathered} \frac{8}{100}\times244.95=19.56 \\ 244.95-19.56=225.39 \end{gathered}$

Therefore the total cost of the tent is $225.39.

Veronika [31]

If it costs 3n+5, you have to plug 7 in for n and solve. 3(7)+5=26 so $26
