Answer:
<A = 18.6 Degree
<B =74.4 Degree
<C = 87 Degree
Step-by-step explanation:
Sum of all the angles of triangle is 180
as given ,
<A = ?
<B = 4<A
<C = 5 <A - 6
As per rule ,
<A + <B +<C = 180
<A + 4 <A + 5<A - 6 = 180
10 <A - 6 = 180
10 <A = 180 + 6
<A = 186 / 10
<A = 18.6 Degree
Hence ,
< B = 4 X (18.6)
< B = 74.4 Degree
and
<C = 5 (18.6) - 6
<C = 87 Degree
PROOF
<A + <B + <C = 180
18.6 + 74.4 + 87 = 180
180 = 180
Answer:
30 girls
Step-by-step explanation:
10 x 2= 20
15x2=30
For every 10 boys there are 15 girls. since 20 is just 10 multiplied by 2 you can multiply 15 by 2
1. 2² times 7¹
2. 2² times 3²
3. 29 is a prime number already
4. 2¹ times 5¹ times 7¹
5. 5¹ times 11¹
6. 3⁴
7. 2³ times 3¹ times 7¹
8. 3² times 11¹
9. 3¹ times 5²
10. 2⁶
