The way that I memorised how to do sin, cos, and tan is by the following: SOH, CAH, TOA

SOH = Sin is OPPOSITE / HYPOTENUSE

CAH = Cos is ADJACENT / HYPOTENUSE

TOA = Tan is OPPOSITE / ADJACENT

For example if we were to solve question 5

Sin T = 6 root 2 / 19

Cos T = 17 / 19

Tan T = 6 root 2 / 17

Repeat the steps for question 6

For the rest of the questions (7,8,9) you have to take the information given and figure out if you should us Sin, cos, or Tan. then plug the numbers in the calculator and while doing sin ^ -1, cos ^ -1, tan ^ -1

for example on question 7, to find the angle x they have given you the hypotenuse and the adjacent side so

cos x = 9 / 18

to find x plug: cos^-1 (9/18) in the calculator

Vladimir [108]

Answer:

The height of Julio greater than the height of Frieda .

Step-by-step explanation:

Given height as :

The height of Frieda = 5 $\frac{1}{4}$ ft

The height of Julio = 5 $\frac{5}{6}$ ft

So, The height of Frieda = 5 $\frac{1}{4}$

= 5 + $\frac{1}{4}$

= $\frac{20+1}{4}$

= $\frac{21}{4}$ feet

∴ The height of Frieda = 5.25 feet

And The height of Julio = 5 $\frac{5}{6}$ ft

So, The height of Julio = 5 $\frac{5}{6}$

= 5 + $\frac{5}{6}$

= $\frac{30+5}{6}$

= $\frac{35}{6}$ feet

∴ The height of Julio = 5.83 feet

Since 5.83 feet $>$ 5.25 feet

So the height of Julio $>$ the height of Frieda

Hence The height of Julio greater than the height of Frieda . Answer

Answer:

(B) ASA

Step-by-step explanation:

we will verify each options

option-A:

we can see that there is no consecutive two angles

so, this postulates can not be true

so, this is FALSE

option-B:

We can see that

one angle and then side and another angle are equivalents

so, this is TRUE

option-C:

We can see that

one side and two angles are equivalents

so, this is FALSE

option-D:

we can see that

one side and two angles are equivalents

so, this is FALSE
