Answer:
3.92 approximately 4
Step-by-step explanation:
let us first find angle at F
40⁰+50⁰+F= 180 (sum of angles in a triangle)
90⁰+F= 180⁰
F= 180⁰-90⁰
F = 90⁰
using sine rule
3/sin 50 = x/sin 90
3/0.7660= x/ 1
0.7660x=3
x= 3/0.7660
x= 3.92 approximately 4
Answer:
50º
Step-by-step explanation:
Angle D & B are vertical angles, meaning they are equal in measure.
So if Angle B = 50º, then Angle D must also be 50º.
Hope this helps! Have a great day!
.21 times 611=128.31
128.31 plus 611
739.31
Answer:
18 - (-12)
Step-by-step explanation:
Final temp. - Initial temp. = the change in temperature
By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...
18 - (-12) = 30
So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.
