Answer:

158 degrees

Step-by-step explanation:

Here, we want to find the sum of the two angles.

If A is a supplement of B, it means that adding A and B together will yield 180 degrees

Mathematically;

A + B = 180

A + 124 = 180

A = 180-124

A = 56

Also, A is a complement of C

This means that adding A to C yields 90

A + C = 90

C = 90- A = 90 -56 = 34

Thus B + C = 34 + 124 = 158

Answer:

The value of DC is 66.34.

Step-by-step explanation:

The triangles ABC and DCA are right angled triangles.

The straight line AC is a bisector for angles C and A.

The measure of ∠C is 30°.

Then the measure of angles BCA and ACD will be 15° each.

The measure of angle DAB is 150°.

Then the measure of angles DAC and BAC will be 75° each.

Now consider the right angled triangle ABC.

The measure of side AC is:

AC^{2}=AB^{2}+BC^{2}\\AC=\sqrt{AB^{2}+BC^{2}}\\=\sqrt{4^{2}+(10\sqrt{3})^{2}}\\=\sqrt{316}

Consider the right angled triangle DCA.

The angle DAC measure 75°.

Using the trigonometric identities compute the value of Perpendicular DC as follows:

tan\ 75^{o}=\frac{DC}{\sqrt{316}}\\\\DC=3.732\times\sqrt{316}\\\\DC=66.34

Thus, the value of DC is 66.34.

Does it matter which dimensions you select for the lenght and the width when you find the area of a rectangle? Explain
Levart [38]
It does not. So Long as the length is multipled by the height aka Long edge multiplied with the short edge, you will obtain the area of the rectangle.
