Answer:
15•4 mm
Step-by-step explanation:
using sine rule
a÷ sinA=c ÷sinC
15•4÷sin90=0•5÷sinC
sinC =0•5 × sin90 ÷ 15•4
C =1•9°
A+B+C= 180
90+B+1•9=180
B= 88•2°
b÷sinB = a÷sinA
b÷sin88•2= 15•4÷sin90
b=sin88•2 ×15•4 ÷sin90
b =15•39
to 1 dp
b =15•4 mm
The 2nd decimal place is 5 so we add one to first deicimal place
Answer is 4.3
Answer:
Step-by-step explanation:
The equations of lines are :
y=4x-5 and y=ax+2
From above equations,
4x-5 = ax+2
4x-ax = 5+2
4x-7 = ax
So, the value of a is equal to 
.

Answer is the ratio 9:14</h3>
Work Shown:
1 foot = 12 inches
3 feet = 36 inches, multiply both sides by 3
The "3 feet to 56 inches" is equivalent to "36 inches to 56 inches".
Then we can form the ratio 36:56. Divide both parts of that ratio by the GCF 4 and we get the reduced ratio 9:14
