Answer:

∠C=79°

∠B=∠D=101°

Step-by-step explanation:

-A parallelogram has a pair of parallel opposite sides.

-It's opposite angles are also equal.

#Given the parallelogram ABCD, and that angle A=79°, the remaining angles can be found as:

Angle A is opposite to angle C

Hence ∠C=79°

#Since it's a parallelogram , the two remaining angles are opposite and equal:

Hence ∠B=∠D=101°

Answer:

m∠B = 101

m∠C =  79

m∠D =  101

Answer:

T=4B+10C

Final answer:

You can solve the quadratic equation using the quadratic formula. For the system of three equations, use basic algebra according to the given condition. The equation involving sum of products can be solved by performing individual multiplications and then calculating the sum.

Explanation:

To help you understand and solve these mathematical equations, let's break them down. For the

quadratic equation

4.90t² + 20t +c = 0, you can use the quadratic formula to find the values of t. It's important to note here that the quadratic formula is [-b ± sqrt(b² - 4ac)] / (2a).

Also, given the system of three equations and three unknowns (Qd, Qs, and P), you can solve these using basic algebra. With Qd = Qs you can set the demand and supply equations equal to each other: 16 - 2P = 2 + 5P. You can then rearrange and solve for P.

Lastly, you have an equation where calculation of the sum of the products is involved: 1(.35) + 2(.20) + 3(.15) + 4(.15) + 5(.10) + 6(.05) = 2.6 years. This means that each number is multiplied by the corresponding percentage and then all results are added up.

As for a specific equation, I could not say. However, I can tell you how to find x!

The first thing to remember is that a straight line has a 180 degree angle.

You see on the bottom side that we have a 146 degree angle. Now look at the top side. Look closely, and you will see that the two sides are actually identical!

Don't see it? Look at the line on top between x and 56, and imagine it is not there. You see that we actually have the same 146 degree angle, just flipped right side up!

However, this angle does not say 146, but makes an extra line between them with x and 56. This means that x + 56 equals 146!

So we can find x by subtracting 56, from 146, which is... 90!
