Answer:
The correct option is option (c).
Step-by-step explanation:
Right angled triangle:
- One angle must be 90° and other two angles are acute angle.
- The hypotenuses is the longest side of the triangle and opposite right angle.
- It follows the Pythagorean Theorem.
Given that,
∠QRP= 90°, ∠RPQ= 30°, ∠PQR = 60°
we know that,
for sin P , the opposite is QR.
The hypotenuse is PQ.
Therefore,

<u>Answer:</u>
The measure of the supplement of an angle is 20° More than three times the measure of the original angle. The angles are 40 degrees and 140 degrees.
<u>Solution:</u>
Given, The measure of the supplement of an angle is 20° More than three times the measure of the original angle.
We have to Find the measures of the angles.
Let the original angle be n degrees.
We know that, sum of supplementary angles is 180, then, supplementary angle of n will be 180 – n.
Now according to the given information, 180 – n = 20 + 3 x n
180 – n = 20 + 3n
3n + n = 180 – 20
4n = 160
n = 40
Then, supplementary angle is 180 – 40 = 140 degrees.
Hence, the measures of two supplementary angles are 40 degrees and 140 degrees.
Answer:
F = 120 N
Step-by-step explanation:
Given that,
The mass of the object, m = 20 kg
Acceleration of the object, a = 6 m/s²
We need to find the force exerted on an object. The force exerted on an object is given by :
So, the required force exerted on the object is 120 N.
