Actually Welcome to the Concept of the Linearity.
Since, we know that, 20+16=36,
hemce, also 4(5+4)= 4*9=36
hence option is G. 4(5+4)
Answer:
They are moving 2 m/s
Step-by-step explanation:
the answer is in the format m/s or meters per second. so in this case, just divide the seconds by the meters
Answer:
41° and 49°
Step-by-step explanation:
Given:
Angle 1 and angle 2 are complementary angles.
The measures of angle 1 is 8 more than the measure of angle 2.
Question asked:
Determine the measures of angle 1 and 2.
Solution:
Let ∠1 = 
Then ∠2 =
(given)
As we know that sum of complementary angles are 90° and here given that angle 1 and angle 2 are complementary angles which means,
∠1 + ∠2 = 90°
°
°
Subtracting both sides by 8,
°
°
Dividing both sides by 2,
°
∠1 =
°
∠2 = 
∠2 =
= 49°
Therefore, the measures of angle 1 and 2 are 41° and 49°
Answer:
the sine of the angle of one corner equals the opposite side divided by the hypotenuse.
the cosine of the angle of one corner equals the adjacent side divided by the hypotenuse.
the tangent of the angle of one corner equals the opposite side divided by the adjacent side.
Check the picture below.
since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.
