Question 11a)

We are given side BC equals to side CE and angle CBA equals to angle CED
We also know that angle ACB equals to angle ECD are equal (opposite angles properties)

We have enough information to deduce that triangle ABC and triangle CDE are equal by postulate Angle-Side-Angle (ASA)

---------------------------------------------------------------------------------------------------------------

Question 11b)

We are given side AB equal to side ED, side BC equals to side EF, and side AC equals to side DF
We have enough information to deduce that triangle ABC and triangle DEF congruent by postulate Side-Side-Side (SSS)

----------------------------------------------------------------------------------------------------------------

Question 11c)

We are given side AC equals to side DF, angle ABC equals to angle DEF, and angle BAC equals to angle EDF

We have enough information to deduce that triangle ABC congruent to triangle DEF by postulate Angle-Side-Angle (ASA)

-----------------------------------------------------------------------------------------------------------------

Question 11d)

Find the missing side. Round it to the nearest tenth
Klio2033 [76]
Answer: 53.6

Explanation:

When given a side and its opposing angle and another angle, to find its opposing side you may use the sine rule.

sin(Angle)/opposing side = sin(Angle)/opposing side

Applying this formula will give us the following:

1) sin90/x = sin66/49
2) 1/x = 0.01864
3) 1/0.01864 = x
4) x ≈ 53.6

Hope this helps, brainliest would be appreciated :)

If the cost of the materials for a basic bar of soap is $2.50 and Lyndi sells each bar of soap for $4.50, what is the markup per
Nadusha1986 [10]

Answer:

80%

Step-by-step explanation:

Cost of materials for a bar of soap = $ 2.50

Selling price for a bar of soap = $ 4.50

Markup percent = \frac{selling\ price\ per\ unit - cost\ per\ unit}{cost\ per\ unit} \times 100

Markup percent = \frac{4.50-2.50}{2.50} \times 100

= \frac{2}{2.50} \times 100

= \frac{200}{250} \times 100

= 20 \times 4

= 80<em>% </em>
