Answer:
Step-by-step explanation:
area of square=10.75² m²
or A=(10.75)(10.75) m²
Find the last angle:
180-(30+90)
180-(120)
60
Evaluate using sine rule:
![\frac{c}{sinC}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bc%7D%7BsinC%7D%20)
=
![\frac{b}{sinB}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bb%7D%7BsinB%7D%20)
c=
![\frac{bsinC}{sinB}](https://tex.z-dn.net/?f=%20%5Cfrac%7BbsinC%7D%7BsinB%7D%20)
=
![\frac{10sin90°}{sin30°}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10sin90%C2%B0%7D%7Bsin30%C2%B0%7D%20)
=20
The length of line segment AB is 20 feet (answer choice C)
Answer:
Mark gets £54
Step-by-step explanation:
Let Gavin share=x
Henry=3x
Mark=2(3x)
x+3x+2(3x)=£90
x+3x+6x=£90
10x=£90
x=9
Gavin=x=£9
Henry=3x
=3(9)=£27
Mark=2(3x)
=2(3*9)
=2(27)
=£54
Answer:
10%
Step-by-step explanation:
50+50=100
45+45=90
100-90=10
Divide the figure into 3 shapes
top square
middle trapezoid
bottom rectangle
so
Area of figure
= (10x10) + 1/2(8 + 14)(4) + (20 x 6)
= 100 + 44 + 120
= 264
answer
264 cm^2
