7(4 + 5) = 63
28 + 35 fits the criteria for your question.
The little lines through the two sides of the triangle mean the sides are equal length.
Because the sides are equal, the two bottom angles are also the same.
Since angle B is given as 46 degrees, angle C is also 46 degrees.
The three inside angles of a triangle need to equal 180 degrees.
Angle A = 180 - 46 - 46 = 88 degrees.
Answer:
and 
Step-by-step explanation:
At=As+Ar; A=b.h and
, then: At=(x+120)x so
(x+120)x=4500,
Applying cuadratic equation formula:
Answer:
Step-by-step explanation:
Good evening ,
I guess it’s the C expression,
Because, C. 3n^2+n-2 so the coefficient of the term n is 1 and the coefficient of the term n^2 is 3
