Answer:
b = 15°
Step-by-step explanation:
The base angles (c = ∠QRP) of ΔQPR are such that the sum of angles of the triangle is 180°. Since the triangle isosceles, the base angles are equal:
2c +60 = 180
2c = 120
c = 60 . . . . . . degrees; the base angle of ΔQPR
__
Likewise, the base angle (∠SRP) of ΔSPR is ...
a = (180 -90)/2 = 45 . . . . . degrees
__
The measure of angle b is the difference between the larger and smaller base angles:
b = c -a = 60° -45°
b = 15°
Answer:
104
Step-by-step explanation:
Answer:
D 62.5
Step-by-step explanation:
Triangles ABE and and DCE are similar
we know this by AAA theorem
A=D and B=C by alternate interior angles theorem
e and e are congruent by vertical angles theorem since all 2 angles match corresponding angles, the are similar, which means the triangle and corresponding sides are also proportional
Answer:
x = 1/14
Step-by-step explanation:
You can work it as is by subtacting ln(14), then taking antilogs:
ln(x) = -ln(14)
x = 14^-1
x = 1/14
___
Or you can rewrite to a single log and then take antilogs:
ln(14x) = 0
14x = 1
x = 1/14 . . . . . divide by the coeffient of x
