Find the missing measure in the triangle with the given angle measures. 45°, 35°, xº
a. 90
b. 10
c. 280
d. 100

d. 100

Step-by-step explanation:

According to angle sum property of a triangle;

45° + 35° + x° = 180°

80° + x° = 180°

x° = 180° - 80°

x° = 100°

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
