First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65
Answer:
B
Step-by-step explanation:
In a parellelogram opposite angles are always equal
Answer:
48.6
Step-by-step explanation:
(1÷5)×243=48.6
The standard size of the rectangle's area is x² + 12x + 35
Given:
a diagram that depicts the polynomial that denotes a rectangle's length and width.
The rectangle's area is equal to its length x width.
Given that length is equal to x + 7 and width is equal to x + 5, the area is equal to length plus width.
Add the numbers in brackets: Area = x2 + 5x + 7x + 35
Area = x2 + 12x + 35
A quadrilateral with equal angles and parallel opposite sides is referred to as a rectangle. We are surrounded by numerous rectangular objects. The length and width of a rectangular shape are the two dimensions that define it. The rectangle's length and width are its longer and shorter sides, respectively. We will learn about the properties of the rectangle shape in this chapter.
