Answer:

64.87° = 65°{ to the nearest degree}

Step-by-step explanation:

From the figure Catherine is standing 105m from the point B where the Ballon is; this description fits a= 105 m from the diagram.

Similarly Aisha is standing 95m from the point B where the Ballon is; this description fits c= 95 m from the diagram

A = ? ( The angle of elevation of Aisha towards the balloon)

C = 55°

From Sine rule

It states that the sine of an angle divided by its corresponding side is equal for all corresponding angles and sides along the triangle.

This is expressed mathematically as;

Sin A/ a= SinB/ b= SinC/c

We take the pairs of relevance;

Sin A/ a = SinC/c

There SinA = SinC/c × a

=Sin55/95 × 105

= 0.9053

A = Sin^(-1)[0.9053]

A = 64.87° = 65°{ to the nearest degree}

Maru [420]

Answer:

The answers are as follows: 12 106 42

Step-by-step explanation:

Given: $ 18 - 4^2 + 5 \times 2 $  

Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate $ 18 - 4^2 $ separately and $ 5 \times 2 $ separately and add them. So we have $ 18 - 16 + 10 = 2 + 10 =12 $.

Now for the second question: $ 9^2 + 4 \times 7 - 3 $. we would get $ 81 + 28 - 3 = 106 $

Next, $ 5^2 - 4 + 7 \times 3 $. This could be written as:  $ 25 - 4 + 21 = 42 $. Hence the answers.

Answer: C) 1560

Step-by-step explanation:

So the first part is splitting the rectangle from the triangle so the area for the rectangle is 1440 (40 x 36) and the area for the triangle is 120 ((6x40)/ 2)

when you add them up the equal 1560 (1440 + 120)
