Answer:
no
Step-by-step explanation:
every triangles degrees equal 180.
78+21=99
180-99=81
the smaller triangle
21+80= 101
180-101=79
so the degrees are different
Answer:
11
Step-by-step explanation:
Constant of proportionality, k, is the ratio of the quantity of variable y to the quantity of variable x.
Using a point on the line, (4, 44),
Constant of proportionality, k = 
.
Constant of proportionality of the graph is 11.
Answer:
18
Step-by-step explanation:
16 |‾‾‾288‾‾‾
16 goes into 28 once = 1 (as the tens digit = 10)
28-16=12 (remainder)
128/16 =8
10 + 8 = 18
Answer: spinning a spinner with 4 equal sections 50 times
Step-by-step explanation:
The models that one can use to simulate the outcome of guessing the correct answers to a 50-question test will be to spinn a spinner with 4 equal sections 50 times.
Flipping a coin 50 times is wrong since the coin only has two outcomes which are head and tail. Rolling a 6-sided die 50 times is also wrong.
Therefore, the correct option is B.
Answer:
63.4°
Step-by-step explanation:
Given that AB and BC are the legs of the right triangle, then opposite to angle A is side BC and adjacent to angle A is side AB.
By definition, the tangent of angle A is:
tan(∠A) = opposite leg / adjacent leg
tan(∠A) = BC/AB
tan(∠A) = 12/6
∠A = arctan(2)
∠A = 63.4°
