I need help with Q11 I’m not sure if I did the calculations right because the area seems way to high
liubo4ka [24]

Answer:

The are a is 6

The length of h = 2.4

Step-by-step explanation:

This is a 3 4 5 special triangle so the length of the hypotenuse is 5

The area for a triangle is calculated by multiplying height to the base and that divided by two

Since it's a right triangle we can take any side length as the height and the result wouldn't change

4×3÷2 = 6 is the area for this triangle now we can use thus information to find the length of h :

h × 5 ÷ 2 = 6

5h = 12

h = 2.4

1/7 divided by what equals 14
posledela
Assume the number we are looking for in n
we want to know the value of n that makes 1/7 divided by n is 14

Transforming this to an equation:
(1/7) / n = 14
this means that:
1/7 = 14n
1 = 7 x 14n
1 = 98n
n = 1/98

Therefore:
1/7 divided by 1/98 will give us 14

\cfrac{a}{\sin(a)} = \cfrac{b}{\sin(b)} 


\cfrac{31}{\sin(42)} = \cfrac{37}{\sin(x)} 


31\sin(x) = 37 \sin(42)

\sin(x) = \cfrac{37 \sin(42) }{31}

x = \sin^{-1}(\cfrac{37 \sin(42) }{31} )

x = 53 \textdegree

Answer: 53°
