Answer:
15π/4
9π /4
Step-by-step explanation:
= 5 ((-π/4)+ π) = 5 (π-π/4) = 5(3π/4) = 15π/4
= 5(π/4 + 2π) = 5(9π /4) = 45π/4
Answer:
Solution given:
angle : 80°
hypotenuse:y=?
opposite=21
we have
Sin 80=
doing crisscrossed multiplication
we get
y=
<u>y=21.32</u>
Answer:
y=8
x=20
Step-by-step explanation:
8y+6=70
5x-10=90

Answer:
(a) 315°
(b) 3°
(c) 238°
Step-by-step explanation:
Bearings are measured clockwise from north. The triangle described is illustrated in the attachment.
<h3>(a)</h3>
The bearing of P from R is 180° different from the bearing of R from P it will be ...
135° +180° = 315° . . . . bearing of P from R
__
<h3>(b)</h3>
The bearing of Q from R is 48° more than the bearing of P from R, so is ...
315° +48° = 363°, or 3° . . . . bearing of Q from R
__
<h3>(c)</h3>
The angle QPR has a value that makes the sum of angles in the triangle equal to 180°. It is ...
180° -48° -55° = 77°
The bearing of Q from P is 77° less than the bearing of R from P, so is ...
135° -77° = 58°
As above, the reverse bearing from Q to P is ...
58° +180° = 238° . . . . bearing of P from Q
