Look at the picture.

$\Delta ADC\ and\ \Delta CDB\ are\ similar\ therefore\\\\\dfrac{y}{4}=\dfrac{9}{y}\ \ \ \ |cross\ multiply\\\\y\cdot y=4\cdot9\\\\y^2=36\to y=\sqrt{36}\to y=6$

A 60-foot tree casts a shadow 85 feet long. The sine of the angle between the ground and the line that connects the tip of the s

s2008m [1.1K]

so leg A would be 60

leg B would be 85

using this we are able to determine the HYP to be 104.04

so sine = opp/HYP

leg A is the opp in this case

sin(theta) = 60/104.04

sin(theta) = 0.57670126874

when we round to the hundredths place we get 0.58

Find the midpoint of H(13,8) and X(-6,-6)

GrogVix [38]

$coordinates\ of\ midpoint \ M(x,y)\\\\ 
endpoint:\ A(13,8)\\
endpoint:\ B(-6,-6) \\\\ 
M(x,y)=(\frac{x_A+x_B}{2}\ ;\ \frac{y_A+y_B}{2})\\\\
M=(\frac{13-6}{2},\frac{8-6}{2})\\\\
M=(3.5;1)$

Richard & Tanjeev share a lottery win of £5650 in the ratio 4 : 1. Richard then shares his part between himself, his wife &a

lidiya [134]

Answer:

Answer is 904

Refer below.

Step-by-step explanation:

5650 total,

And 4:1 which adds up and make 5. So,

5x = 5650

x=5650/5

x=1130

As pichard part is 4:1 so his part is 4 overall the money so,

Richard got 4x = 4 × 1130 = 4520

4520 now dividing in 6:3:1

10a = 4520

A= 452

Wife amount is 3a = 3 ×452 = 1356

Son is 1a so its,

Son = 452

Minus= 1356 -452 = 904

Wife got 904 more than son
