Answer:

x ≈ 46.7°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x = $\frac{opposite}{hypotenuse}$ = $\frac{OP}{NP}$ = $\frac{4}{5.5}$ , then

x = $sin^{-1}$ ( $\frac{4}{5.5}$ ) ≈ 46.7° ( to the nearest tenth )

The triangle has size with the lengths of 3 cm 13 cm and 14 cm Is it a right triangle?

WITCHER [35]

Answer:

No, it is not a right triangle

Step-by-step explanation:

Let H = 14 cm

B = 3 cm

P = 13 cm

According to pythagoras theorem:

H^2 = P^2 + B^2

14^2 = 13^2 + 3^2

196 = 169 + 9

196 is not equal to 178

Hence, it is not a right triangle

The arithmetic mean (average) of four numbers is 85. If the largest of these numbers is 97, find the mean of the remaining three

Margaret [11]

Answer:

Step-by-step explanation:

Let's do this systematically:

Four numbers: a, b, c, d

Whose mean is 85: $\frac{a + b + c + d}{4} = 85$

Whose largest number is 97: $\frac{a + b + c + 97}{4} = 85$

Lets solve for the other numbers:

a+b+c+97 = 85*4 = 340

340 - 97 = 243

a+b+c = 243

at this point it doesn't matter what the numbers are, they just need to add up to 243.

We can do 243÷3=81, which is our answer
