Pleaseee help help

Eddi Din [679]

The angle the golfer went off line from the tee when they drove the ball

is $\phi=28.2 \textdegree$ because the cosine rule has been applied to calculate the angle

From the question we are told that:

Distance of hole from tee $d_h=340yards$

Distance to the right $d_r=230yards$

Ball distance from hole $d_b=175 yard$

Given that the three points form a triangle x,y,z respectively

Where

$d_h=xz$

$d_r=xy$

$d_b=yz$

Using Cosine Rule

$yz^2=xy^2+xz^2-2(xy)(xz)cos\phi$

Therefore

$cos\phi=\frac{yz^2}{xy^2+xz^2-2(xy)(xz)}$

$cos\phi=\frac{(175)^2}{230^2+340^2-2(230)(340)}$

$cos\phi=0.88$

$\phi=28.2 \textdegree$

In conclusion the angle the golfer went off line from the tee when they

drove the ball is mathematically deducted and give as

$\phi=28.2 \textdegree$

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.96, and and they leave a 20

Karolina [17]

Multiply the cost by 1.2 (120%) to add 20% tip, and then multiply by 0.85 (85%) to take off 15%

78.96 x 1.2 x 0.85 = 80.54

Answer:

Hence the correct option is 3rd option. 40

Step-by-step explanation:

If two figures are similar, then the ratio of the corresponding sides is proportional.

$\frac{15}{30} =\frac{20}{n} \\\\n=\frac{30 \times 20}{15} \\\\n= 40.$
