-85 degrees in is the 4th quadrant so the cos and sec will be positive
sec is also positive in first quadrant so sec(85) will be equal to sec(-85)
Sec is is negative in 3rd quadrant so -sec(-95) will be same also.
sec 275 is in 3rd quadrant so will be negative so not equal
also sec(-95) will be same angle as sec 275
the last 2 options are not equal to sec(-85)
Answer:
C
Step-by-step explanation:
Answer:
The equation for this problem in slope intercept form is y=6
Step-by-step explanation:
since the equation for slope intercept is y=m(x)+b and x is the slope, and x equals 0, the only logical answer for this problem would be y=6 because there is no rise over run in this equation only the y intercept which in slope intercept form, the y intercept equals b. so in usual terms it would be y=m(x)+b but there isn't any m(x) in this particular equation, therefore, making the equation just y=b so y=6
Answer:
Step-by-step explanation:
if you've any doubt just ask :)
See explanations.
Step-by-step explanation:
1. Triangles are similar
Reason: corresponding angles are equal/congruent.This means;
∠A≅∠D , ∠C≅∠F and ∠B≅∠E
2.
a) Triangles are similar
Reason: corresponding angles are congruent.
15/5 =a/3
3=a/3
3*3=a
a=9cm
b) Triangles are similar because angles in corresponding sides are congruent.
20/12=15/b
20b=12*15 -----cross product applied
20b=180
b=180/20
b=9 cm
c) Triangles are because angles in corresponding sides are congruent.
15/5=d/4
cross product
15*4=5d
60=5d
60/5 =d
12m =d
