Answer:
B = 75°
Step-by-step explanation:
Using the Sine rule:
a / sin A = b / sin B = c / Sin C
a / sin A = b / sin B
20 / sin 48 = 26 / sin B
Cross multiply :
Sin B * 20 = sin 48 * 26
Sin B = (sin 48 * 26) / 20
Sin B = 0.9660882
B = sin^-1(0.9660882)
B = 75.036
B = 75°
For the second work sheet:
5 2/8 - 4 1/4= 1 so NO
8 3/4 - 7 1/2= 1 1/4 so YES
2 1/8 - 1 7/8= 1/4 so NO
9 5/12 - 8 1/6= 1 1/4 so YES
Sorry if its not enough explanation, hope it helps!
Answer:
q=(40-7)/3 or simplified q=11
Step-by-step explanation:
So we know that the perimeter is 40 inches and one of the sides is 7 so logically we do 40-7 to get the length of the three remaining sides combined. Then to find the length q, we have to divide that answer by 3 because the three sides have the same length or (40-7)/3, which simplified is 11, so the length of the side is 11 inches and the expression is q=(40-7)/3.
Answer:
15 2/3
Step-by-step explanation:
11 feet + 4 2/3 feet = 15 2/3
11+4= 15 + 2/3 = 15 2/3
Its actually very simple.
