A straight line is 180°, so you can do:
109 + ? = 180 (? is the top angle of the triangle)
? = 71°
Because the triangle is an isosceles triangle, the other angle is 71° too.
71 + 71 + ? = 180
? = 38
You subtract 38 with 90 to find the other angle.
90 - 38 = 52°
To find ∠2 you subtract 52 with 180.
180 - 52 = 128
∠2 = 128
128 = 11x + 18
110 = 11x
10 = x
Answer:
A
Step-by-step explanation:
The explicit formula for a geometric sequence is
f(n) = f(1) 
where f(1) is the first term and r the common ratio
Here f(1) = 64 and r = 
= 
= 
, then
f(n) = 64 
→ A
1 pint is equal 16 oz, so 16/0.75 is approximately 21.33 days so it would last 21 days.
Answer:
Just two
Step-by-step explanation:
Glorias teacher asks her to draw a triangle with 90 degree angle and a 42 degree angle.
The presence of 90 degrees indicates that it's a right angle triangle.
The remaining angle= 180-90-42
The remaining angle= 48 degrees
Due to the presence of 90 degrees, the angle 42 and 48 degrees will interchange two times only to form only two unique triangles.
