Answer:
OD) 4.9 units, 14.2 units
<em> The lengths of the legs of a right triangle</em>
<em> </em>a = 4.9units , b = 14.2units and hypotenuse 'c' = 15
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the Acute angle is 19°
And hypotenuse (AC ) = c= 15
We will take cos∝ = 
⇒ 
⇒ BC = 15 × cos 19°
⇒ BC = 15 ×0.9455
⇒ BC = 14.18
The length of the one leg of the right angle triangle
BC = b = 14.18≅ 14.2
We know that ΔABC is a right angle triangle
a² = c² - b²
= 15² - (14.18)²
= 225 - 201.07
= 23.93
a² = 23.93
a = √23.93 = 4.89≅4.9
<u><em>Final answer:-</em></u>
<em> The lengths of the legs of a right triangle</em>
<em> </em>a = 4.9units , b = 14.2units and hypotenuse 'c' = 15
Answer: 38.9
Step-by-step explanation:
Add all the numbers together and divide the sum by how many numbers there are.
9÷0.001 is greater than 8÷0.001.
7÷0.001 is less than 8÷0.001.
8÷0.002 lie between 8÷0.001 and 8÷110.
A ratio can be written in three different ways: 3 to 4, 3:4, and 3/4
What does this mean? It means that for every group of 7 students (3+4) there are 3 boys and 4 girls. And how many groups do we have? We have:
245/7= 35 We have 35 groups, and we just said that each group has 3 boys and 4 girls:
35*3= 105 boys
35*4= 140 girls

Answer:
option-c
Step-by-step explanation:
we are given
we will verify each options
option-A:
we can see that exponent is over 3
and it is positive and greater than 1
so, this function is increasing
so, this is FALSE
option-C:
At x=1:
At x=2:
So, it is getting tripled
so, this is TRUE
option-b:
we can plug x=0
so, this is FALSE
option-d:
we can plug x=1
so, this is FALSE
