4. Determine all unknown sides and angles to 1 decimal place.

Ksju [112]

Answer:

The unknown sides are 60.81cm and 51.57cm while the unknown angle is 58degrees

Step-by-step explanation:

4a) Given the following

Opposite side = 38cm (side facing the given angle)

Required

Adjacent and hypotenuse side

According to SOH CAH TOA

$tan \theta = \frac{opp}{hyp}\\tan 32=\frac{38}{hyp}\\hyp=\frac{38}{tan 32}\\hyp=\frac{38}{0.6249}\\hyp= 60.81cm$

Next is to get the adjacent

$Cos 32=\frac{adj}{60.81}\\adj=60.81cos32\\adj=60.81(0.8480)\\adj= 51.57cm$

Next is to get the missing

Since sum of angle in the triangle is 180degrees

32 + 90 + x = 180

122 + x = 180

x = 180 - 122

x = 58degrees

For a diamond problem what two numbers' sums equal 31 and their product is 234?

s344n2d4d5 [400]

Let

x-------> the first number

y------> the second number

we know that

$x+y=31$

$x=31-y$

equation $1$

$x*y=234$

equation $2$

substitute equation 1 in equation 2

$(31-y)*y=234\\ 31y-y^{2} =234\\ -y^{2} +31y-234=0$

using a graph tool-----> to resolve the second order equation

see the attached figure

the solution is

$13 and 18$
