You can use the Angle-Side-Angle (ASA) Congruence Postulate to prove the triangles are congruent.
Answer:
70 degrees
Step-by-step explanation:
The angle opposite x and x itself are vertical angles, meaning that they have the same angle measure. Since the sum of the interior angles of a triangle is 180 degrees:
x+55+55=180
x+110=180
x=180-110=70
Hope this helps!
1+2=3
This isn’t hard if u add them together
Answer:the length of the third side is 4√7
Step-by-step explanation:
The perimeter of a triangle is 16 to the square root of 7 feet. This is expressed as
Perimeter = 16√7 feet
The perimeter of a triangle is the sum of the length of the three sides of the triangle.
If the two sides measure the square root of 343 feet and the square root of 175, which are expressed as √343 and √175, the third length would be
16√7 - (√343 + √175)
Expressing √343 as a radical, it becomes 7√7
Expressing √175 as a radical, it becomes 5√7
7√7 + 5√7 = 12√7
Therefore, the third length would be
16√7 - 12√7 = 4√7 feet
Answer:
x = -9
Step-by-step explanation:
the equation is 2^4x = 8^x - 3.
therefore 2^4x = 2^3(x-3)
since both have powers of 2
therefore
4x = 3(x-3)
4x = 3x - 9
4x -3x = -9
x = -9
