Can I see a pic? But 3/2 is like three divided by two so the answer would be 1.5
Step-by-step explanation:
Referring to diagram, we see two isosceles triangles whose vertex angles are complementary (add up to 90 degrees).
Given the base angle of one is 71, we deduce that the other base angles is also 71. Hence the vertex angle is 180-71-71 = 38.
Since the vertex angles are complementary, we deduce that the angle is 52 degrees.
For the second isosceles triangle, the base angles are (180-52)/2 = 64 degrees.
Since 64 degrees and angle 2 are supplementary,
angle 2 measures 180-64 = 116 degrees.
We're given angle2 = 7x+6, so
x= (116-6)/7 = 110/7
= 17.14 degrees (to the hundredth degree).

Answer: Angle B measures 30 degrees.
Step-by-step explanation: First of all, angles A and B are complimentary, which means they both add up to 90. Also the cosine of angle A has been given as 0.5
The value in degrees, of an angle whose cosine is 0.5000 is equal to 60 degrees (this can be verified with a table of values, or by checking the second function Cosine of a calculator).
Where angle A has been determined to be 60 degrees and angles A and B are complimentary, angle B is derived as follows;
Angle A + Angle B = 90 {Complimentary angles equal 90}
60 + Angle B = 90
Subtract 60 from both sides of the equation
Angle B = 30 degrees
