The three inside angles (a,b and c) of a right-angled triangle are in the ratio 7:18:11
svet-max [94.6K]

Answer:

The three angles of the right-angled triangle are

a = 35°

b = 90°

c = 55°

Step-by-step explanation:

We are given the ratio of angles of a right-angled triangle

a:b:c = 7:18:11

Recall that the sum of interior angles in a right-angled triangle is always 180°

7x + 18x + 11x = 180

36x = 180

x = 180/36

x = 5

a:b:c = 7x:18x:11x

a:b:c = 7(5):18(5):11(5)

a:b:c = 35:90:55

a = 35°

b = 90°

c = 55°

Alternatively:

We are given that the smallest angle is 35°

a = 7x = 35

x = 35/7

x = 5

b = 18x

b = 18(5)

b = 90°

c = 11x

c = 11(5)

c = 55°

Interest earned: $294<br> Principal: $600<br> Interest rate: 7%<br> Time:
ICE Princess25 [194]

Answer: 7 years

Step-by-step explanation:

Given the formula for simple interest as

Principal × Rate × Time

To find Time is therefore 100 × Interest/ Principal x Rate

From the above question,

Principal is given as 600;

Interest is 294 and

Rate is 7%

Slot the values into the formula:

100 × 294/ 600 x 7

= 29400/4200

=7

Therefore, Time (T) is 7 years

I hope this is clear, please mark as brainliest

What is the area of this trapezoid?
Oksi-84 [34.3K]

Answer:

The answer is option b 130cm²

Area of a trapezium is 1/2(a + b) × h

where 'a' and 'b' are the parallel sides of the trapezium

h is the height

From the picture above

h is 10cm

'a' and 'b' are 17cm and 9 cm respectively

Area of the trapezium = 1/2 ( 17+9)× 10

= 1/2× 26 × 10

= 13 × 10

= 130cm²

Hope this helps
