Answer:
A
Step-by-step explanation:
Answer:
(i)
<u>Given</u>
<u>Also we see that</u>
- ∠ABC = ∠DBE as refer to same angle
<u>Since two angles of triangles are congruent, the triangles are similar by </u><u>AA similarity postulate</u>
(ii)
<u>In similar figures corresponding parts have same ratio. Use ratios to find the value of x:</u>
- AB/EB = AC/ED
- 12/8 = x / 4
- x = 4*12/8
- x = 6 cm
Im no good at at all but im gonna guess the Second one...sorry if its wrong
Step-by-step explanation:
Eleven times the quantity of a number plus four.
times ( · )
quantity ( ÷ ) or ( / )
Let n - the number
11 · (n ÷ (+4)) or 11 · n/(+4)
30 + 75x= 210
Subtract 30 from both sides
75x=180
Divide both sides by 75
X =2.4
Worked 2.4 hours
