They are -9 and 8. because since 9 times 8 is 72, you need the 9 to be negative to add to -1
Answer:
A. 27 degrees, 63 degrees, 90 degrees.
Step-by-step explanation:
Let the angle of the triangle be x
<u>Given the following data;</u>
3 : 7 : 10 = 3x : 7x : 10x
We know that the sum of the sides of a triangle is equal to 180 degrees.
3x + 7x + 10x = 180
20x = 180
x = 180/20
x = 9
<u><em>For the first side;</em></u>
3x = 3 × 9 = 27°
<em><u>For the second side;</u></em>
7x = 7 × 9 = 63°
<em><u>For the third side;</u></em>
10x = 10 × 9 = 90°
Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.
Answer:
False
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
The 4 part of the ratio represents Pip's 20 sweets
Dividing 20 by 4 gives the value of one part of the ratio
20 ÷ 4 = 5 sweets ← value of 1 part of the ratio
Thus
Pip gets 20 sweets
Angad gets 20 sweets ( 4 parts of the ratio )
Nick gets 5 sweets ( 1 part of the ratio )
Total number of sweets = 20 + 20 + 5 = 45
