Answer:
look at the horizontal line in the picture. the degree measure of any line is 180° given there's a perpendicular ray through that horizontal line it's therfore split into two sides both with angle measure of 90°.
given f is 71° then g can be found knowing that both g and f must add to 90°. 71+g=90. g=19°
now look at f again. f and d are what's known as vertical angles and that means that they're angle measures are congruent. therfore the measure of d is 71° d=71°
Finally to find e we notice that angle d and e form a straight line which means both angles measures must add to 180°. therefore e can be found by computing d+e=180
aunaitituitmg our information we know 71+e=180 then e must equal 109° e=109°
It kind of looks like your missing something in you problem. But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3. So f(4.5) = 3. Most of the time though f(x) means a function of x, so there is an x in the problem. For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
Answer:
1. 90-68= 22
2. 90-80= 10
3. 90-3= 87
Step-by-step explanation:
A complement angle is found by their sum being 90 degrees. So, you are looking for the angle that would add to the given angle to = 90.
Answer:
the shop meet at March at 65
Answer:
Step-by-step explanation:
The bottom leg is divided into equal segments, one of them is b.
It means the bottom leg is b + b = 2b.
<u>According to Pythagorean:</u>
<u>Solve for b:</u>
- 1681 = 4b² + 81
- 4b² = 1681 - 81
- 4b² = 1600
- b² = 400
- b = √400
- b = 20 cm
