Answer:
cos34°
sin56°
Step-by-step explanation:
Sin(2x+42)= sin90-(3x+13)
Sin(2x+42) = sin(90-13-3x)
Sin(2x+42) = sin(77-3x)
2x + 42 = 77-3x
5x. = 35
X = 7
If x = 7
cos(3x+13) = cos((3*7)+13)
cos(3x+13) = cos(21+13)
cos(3x+13)= cos34
And
sin(2x+42) = sin((2*7)+42)
sin(2x+42)= sin (14+42)
sin(2x+42) = sin56
Answer:
a) 300m
b) 15 miles
Step-by-step explanation:
a) 1 : 30 000
= 1x 30 000
= 30 000cm
= 30 000cm/ 100 Representing in metres
= 300m
b) 1 : 6
= 1x 2.5 : 6x 2.5
= 2.5 : 15
= 15 miles
Answer:
a) 3/10
b) 46/100 = 23/50
c) 75/1000
Step-by-step explanation:
A cyclic quadrilateral is a quadrilateral inscribed in a circle
The measure of angle A is 106
<h3>How to determine the measure of angle A</h3>
From the question, we have:
<C= 74
Opposite angles of a cyclic quadrilateral add up to 180.
So, we have:
<A + <C = 180
This gives
<A + 74 =180
Subtract 74 from both sides
<A =106
Hence, the measure of angle A is 106
