Answer:
x is equal to 55 degrees.
Step-by-step explanation:
In order to find this, we must first realize that the angle next to 160 is equal to 20 degrees. This is because they come together to make a straight line, which is equal to 180 degrees.
Now knowing this, we can find the two congruent angles at the top. Since they form one angle of a large triangle along with the right angle and 20 degrees, we know they combine to be worth 70 degrees. Since they are even, we know each is 35 degrees.
For the final step, we know that the 35 degree angle and 90 degree angle form a triangle with x. Knowing these all add up to 180, we can solve for x.
35 + 90 + x = 180
125 + x = 180
x = 55
According to the given expression, the value of b if 
is -1 and + 1
Indices are expressed using exponents and bases. Some of the useful laws of indices are:
Given the expression;
This can also be expressed as:
![b^2=\frac{1}{b^{10}}\\b^2 \times b^{10} =1\\b^{2+10} =1\\b^{12}=1\\b=\pm\sqrt[12]{1}\\b=\pm1](https://tex.z-dn.net/?f=b%5E2%3D%5Cfrac%7B1%7D%7Bb%5E%7B10%7D%7D%5C%5Cb%5E2%20%5Ctimes%20b%5E%7B10%7D%20%3D1%5C%5Cb%5E%7B2%2B10%7D%20%3D1%5C%5Cb%5E%7B12%7D%3D1%5C%5Cb%3D%5Cpm%5Csqrt%5B12%5D%7B1%7D%5C%5Cb%3D%5Cpm1)
Hence the value of b from the given indices is -1 and + 1

Check out the graph below. We see that (3,0) is a root or x intercept. More specifically, the graph only touches the x axis at this point, rather than cross over (in contrast to a root like (-2,0) ). We say that the root here is of multiplicity 2. The multiplicity is due to the exponent of 2 over the (x-3) factor.
You can also say that the graph is decreasing on the left side of (3,0) and then it bounces off the root x = 3 to increase afterward. In this region, the graph never goes below the x axis.
Multiplying decimals is the same as multiplying whole numbers except for the placement of the decimal point in the answer. When you multiply decimals, the decimal point is placed in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.
If both triangles ABE = CBD then <C = <A
Hope it helps.
