Divide the area by the length, which should be 5
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
Answer:
(I only have the answers for 3 and 4) 3. Volume: 192 Surface Area: 16 4. Volume: 1,200 Surface Area: 100
Step-by-step explanation:
3. Volume: 4 x 4 = 16 x 12 = 192 Surface Area: 4 x 4 = 16 4. Volume: 10 x 10 = 100 x 12 = 1,200 Surface Area: 10 x 10 = 100
