Answer:

B, C

Step-by-step explanation:

Let's go through each one to see which is valid

A: Isosceles triangles must have at least 2 sides of the same length. In this case all 3 sides are different. Hence A is NOT valid.

B. Obtuse triangles have one angle which is greater than 90 degrees. In this case, we have one angle greater than 90 degrees (i.e 120 deg). Hence B is valid.

C. Scalene triangles have sides whose lengths are all different. We see this evident in our triangle here. So C is valid.

D. Right triangles must have one angle exactly equal to 90 degree. We do not see this here. So D is NOT valid.

E. Equilateral triangles have 3 sides exactly the same length.We do not see this here. So E is NOT valid.

F.Acute triangles have all angles less than 90 degrees. Here we obviousy have one that is greater than 90 degrees (i.e 120 degrees) hence F is NOT Valid.

17% of what number is 3.4

saw5 [17]

Answer:

Step-by-step explanation:

We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

Step 1 ---> 3.4 = 17% × Y

Step 2 ---> 3.4 = 17/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:

Step 3 ---> Y = 3.4 × 100/17

Step 4 ---> Y = 3.4 × 100 ÷ 17

Step 5 ---> Y = 20

Finally, we have found the value of Y which is 20 and that is our answer.

<h3>*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*</h3>

Define sinA? Wrong answers will be reported . So please give correct answer.

Cloud [144]

Answer:

In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. 

The abbreviation is sin. sin θ = opposite / hypotenuse.2 cosA sinB = sin(A + B) − sin(A − B) 2 cosA cosB = cos(A + B) + cos(A − B) 2 sinA sinB = cos(A − B) − cos(A + B)
