The diagram shows a right angled triangle. 7cm and 11cm and x degrees. Find the size of angle x. Give your answer correct to 1 d

soldier1979 [14.2K]

<h3>Given:</h3>

Hyp= 11 cm
Adj= 7 cm

Hyp= Hypotenuse
Adj= Adjacent

The size of the unknown angle "x".

<h3>Solution:</h3>

We'll have to check which one is appropriate from SOHCAHTOA.

In this question we'll have to use cos because hypotenuse and adjacent is given.

$\large\boxed{cos(A)=\frac{adj}{hyp}}$

Substitute according to the formula.

$cos \: x= \frac{7}{11}$

We'll have to use cos inverse.

$x={cos}^{-1}(\frac{7}{11})$

$x=50.47880364$

$\large\boxed{x=50.5°}$

Therefore, the size of the unknown angle "x" is 50.5°

Hi~! can someone help me with this~?

Answer:

$6.50

Step-by-step explanation:

Let the cost of a bowl and a jug be $b and $j respectively.

3b +j= 13.70 -----(1)

j= b +4.10 -----(2)

Substitute (2) into (1):

3b +b +4.10= 13.70

4b +4.10= 13.70 (simplify)

4b= 13.70 -4.10 (-4.10 on both sides)

4b= 9.60

b= 9.60 ÷4 (÷4 on both sides)

b= 2.40

Substitute b= 2.40 into (2):

j= 2.40 +4.10

j= 6.50

Thus, the jug costs $6.50.
