Answer:
624 inches
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Width = 104 inches
So, Length = 104 × 2 = 208 inches
Now, we can calculate the perimeter of rectangle by using following formula,
Perimeter of rectangle = 2 ( length + width)
By putting the value, we get
Perimeter of rectangle = 2 ( 208 + 104)
= 624 inches
You can use Pythagorean theorem make a triangle
The triangles are always 180 degree so add the 2 and subtract it from 180<span />
Answer:
Step-by-step explanation:
The identical arc symbols on the two angles indicates the angles are congruent. Also, these are alternate interior angles where a transversal crosses lines marked as parallel, so they are congruent:
∠A = ∠B
8x +78° = 2x +114° . . . . . substitute the given expressions
6x = 36° . . . . . . . . . . . . . subtract 2x+78° from both sides
x = 6° . . . . . . divide by 6
∠B = 2x +114° = 2·6° +114° . . . . . put the value of x into the expression
∠B = 126°
