Answer:
∠CAB = 28°
∠DAC = 64°
Step-by-step explanation:
What you do in each case is make use of the relationships you know about angles in a triangle and around parallel lines. You can also use the relationships you know about diagonals in a rectangle, and the triangles they create.
<u>Left</u>
Take advantage of the fact that ∆AEB is isosceles, so the angles at A and B in that triangle are the same. If we call that angle measure x, then we have the sum of angles in that triangle is ...
x + x + ∠AEB = 180°
2x = 180° -124° = 56°
x = 28°
The measure of angle CAB is 28°.

<u>Right</u>
Sides AD and BC are parallel, so diagonal AC can be considered a transversal. The two angles we're concerned with are alternate interior angles, so are congruent.
∠BCA = ∠DAC = 64°
The measure of angle DAC is 64°.
(Another way to look at this is that triangles BCE and DAE are congruent isosceles triangles, so corresponding angles are congruent.)
Using the distributive property, a(b+ c) = ab + ac. In this case, b is 30, so the blank is 30.
Answer:
100 Sq Mt = 1135.69 Sq Ft
Step-by-step explanation:
We are required to find how many square feet are in 100 m squared.
1 meter = 3.37 ft
1 metre x 1 meter = 3.37 x 3.37 Sq ft
1 Sq Mt = 11.3569 Sq ft
100 sq Mt = 100 x 11.3569 sq ft
100 sq mt = 1135.69 Sq ft
Hence
100 Sq Mt = 1135.69 Sq Ft
