given <abd = 48 and <dbc = 78, hence the addition rule is true<abc = <abd + < dbc
Substituting the given values inti the formula;
< abc = 48+78
< abc = 126°
The measure of angle abc is therefore 126°

Answer:
372 m²
Step-by-step explanation:
A vertical line down the center of the figure will divide it into two congruent trapezoids, each with bases 13 and 18, and height 12.
The area of one of them is ...
A = 1/2(b1 +b2)h
So, the area of the two of them together is ...
A = (2)(1/2)(b1 +b2)h = (b1 +b2)h
A = (13 m + 18 m)(12 m) = 372 m²
Answer:4
Step-by-step explanation:
A whole number is a number that is whole as in 1,2,3,4,etc, they don’t have decimals. To find the whole number for these questions you must look at the places (hundreds, thousands, ten thousands.) I was always told a trick which is 4 or less let it rest, 5 or more let it sore. (Basically if it’s less than 4 then decrease it, if it’s higher than increase it.)
12.496 = 13
2.90 = 3
Your answers are 13 and 3.
