Answer:

B 75

Step-by-step explanation:

The three angles of a triangle add to 180 degrees.

35+70+x = 180

Combine like terms

105+x =180

Subtract 105 from each side

105-105+x = 180-105

x = 75

Please solve this...I can;t do it do it

yanalaym [24]

Answer:

Area = 867 meters

Step-by-step explanation:

You have a rectangle. This means opposite sides are equal. If you set these expressions equal to each other, you will get two equations with two unknowns, x and y. Next, solve the system of equations to find x and y. Then, use the values to find the length and width of the rectangle. Last, multiply length × width to find the area.

We use the word argument to refer to a series of reasons given to support a claim. The claim being supported is the conclusion. The reasons given to accept the conclusion are called premises. Analyzing an argument means identifying its premises and conclusion.
