Given that Macy wants to construct an isosceles triangle, with the unique angle being 40° it implies that for the triangle to be isosceles, the base angles should be the same. The size of the base angles will be:
(180-40)/2=70
given that that the base is 6 cm, Macy can only form 1 triangle with these dimensions.
The length of the other sides will be found using sine rule
a/sin A=b/sin B
a=6 cm
A=40°
b=?
B=70
hence:
6/sin 40=b/sin 70
b=(6sin 70)/sin40
b=8.77 cm
Answer:
the weight of 1 textbook is 2 pounds
the weight of 1 game is about 0.5 pounds
Step-by-step explanation:
1/2 of 2 = 0.5 pounds
0.5 times 8 (games) = 4
22 - 4 = 18
18 divided by 9 (textbooks) = 2 pounds
Answer: the answer is 12.3
Step-by-step explanation:
Just do 15/100(82)
X / 90 = 100/36
36x = 9000
x = 9000/36
x = 250 feet
Before you do anything, you convert 1/4 into 0.25. Then you start multiplying. If you don't understand email me at
