Answer:
It should be d=2.25t
Step-by-step explanation:
The question only contains 2.25 not 2 or 4 and also you would multiply it
Answer:
cos60°
Step-by-step explanation:
Using the cofunction identity
cos(90 - x) = sinx , then
sin30° = cos(90 - 30)° = cos60°
Answer:
x=40
Step-by-step explanation:
Angle Formed by Two Secants= 1/2(DIFFERENCE of Intercepted Arcs)
x = 1/2(120-40)
x = 1/2(80)
x = 40
Answer:
<em>120 degrees</em>
Step-by-step explanation:
Find the diagram attached.
From the diagram;
Interior angles are m∠BCA and m∠ABC
Exterior angle is m∠DAB
The sum of interior angle of the triangle is equal to exterior
m∠BCA +m∠ABC =m∠DAB
Given
m∠ABC = 70
m∠BCA =50
m∠DAB = 70 + 50
m∠DAB = 120 degrees
<em>Hence the measure of m∠DAB is 120 degrees</em>
