Step-by-step explanation:
(a)
Sum the parts of the ratio , 1 + 2 + 3 = 6 parts
Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Since there is an angle of 90° then the triangle is right.
(b)
The shortest side is the side opposite the smallest angle of 30°
Using the sine ratio and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2 opp = 19 ( divide both sides by 2 )
opp = 9,5
Shortest side in the triangle is 9.5 cm
Answer:
choice 1
Step-by-step explanation:
Given
V = πr²h ( isolate r² by dividing both sides by πh )
= r² ( take the square root of both sides )
= r ← the positive value of r
Step-by-step explanation:
The formula for percent change is
change/original.
So let's subtract 17 from 55 to find the change. 55-17=38
This is the change. Now we divide it by the original, 17.
38/17=2.235294
We're not done yet! We have to move the decimal point over to the right 2 spaces to make it a percentage. So, the percentage increase is
about 223.53 percent
The answer is false because if you attach to triangles together in a way so that the figure would have 4 straight lines, you will get a rectangle. that means half of a rectangle is a triangle, so the area of both cannot be the same even if they have the same base and height.
for example the base and height of both is 3cm and 5cm.
area of the rectangle then would be,
area= base× height
=3cm×5cm=15cmsquared
then the area of the triangle would be,
area= base×height divided by 2
=3cm×5cm÷2= 7.5cm
so your answer is false
hope this helps....
