Step-by-step explanation:
So, the first step to solving the problem is to find out what type of triangle it is
and what rule of goemetry we can use to solve it.
Finding What Theorem We Can Use
So, the first step is to figure out what theorem we can use to solve the problem and how they can help us. By looking at it, we can see that it is an Isosceles Triangle due to the two sides being equal and 1 side not being equal.
One Theorem used on the Isosceles Triangle is the Base Angles Theorem. This states that the bottom two angles of the sides on the Isosceles triangle are equal to each other. So in this case if we letter the triangle A on the top, B as the Left, and C as the right. It would say this:
Since we know this rule, we can solve for the equation.
Solving
We can solve for this by using two things that we know:
+ Sum of all angles in a triangle is 180 degrees.
+ Bottom two sides are congruent.
Since we know that, we can solve for the answer:
After solving, we know that x is 50 degrees!

Answer:
159
Step-by-step explanation:
Based on process of elimination, it cant be 51 nor 55 because that angle is 100% bigger than 90 degrees. To find it correctly, all you would do is add them. 105 + 54= 159
The percentage of correct answers is 85% and the percentage of incorrect answers is 15% and this can be determined by using the unitary method.
Given :
- Henry takes a math test that had 20 questions.
- He answered 17 questions correctly and 3 questions incorrectly.
The following steps can be used in order to determine the percentage of correct and incorrect questions Henry answered:
Step 1 - The unitary method can be used in order to determine the percentage of correct and incorrect questions Henry answered.
Step 2 - The total number of questions in a math test is 20. The total number of correct answers is 17 and the total number of incorrect answers is 3.
Step 3 - If the 20 is the 100% questions then the percentage of 17 correct answers is:
= 85%
Step 4 - If the 20 is the 100% questions then the percentage of 3 incorrect answers is:
= 15%
