Applying the Pythagorean theorem and the trigonometric ratios, the perimeter of triangle ABC is: 68.8 units.
<h3>What is the Perimeter of a Triangle?</h3>
The perimeter of a triangle = sum of its 3 sides.
Given the following:
Use the Pythagorean theorem to find AD considering triangle ADB as a right triangle:
AD = √(15² - 9²)
AD = 12 units
Use the trigonometric ratios to find DC and AC:
sin 30 = AD/AC
sin 30 = 12/AC
AC = 12/sin 30
AC = 24 units
tan 30 = AD/DC
tan 30 = 12/DC
DC = 12/tan 30
DC ≈ 20.8 units
BC = BD + DC = 9 + 20.8
BC = 29.8 units.
Perimeter of triangle ABC = BC + AB + AC
Perimeter of triangle ABC = 29.8 + 15 + 24
Perimeter of triangle ABC = 68.8 units.

Answer:
P-15>18
P>33
Step-by-step explanation:
First, you need to make the equation. Knowing that deference means you need to subtract, you write it out. P-15>18 . Then to solve it, you add the 15 over to the other side. 18+15=33, therefore p>33
The complete question in the attached figure
we know that
the total the hours--------------- > 9+10+6+13+5=43 hours
Art hours------------->10
Math hours------------->9
Math and Art hours------> 10+9=19
if 43 hours ------------------> 100%
19 hours----------------------> X
X=19*100/43=44.19%---------- > <span>Approximately 45%
</span>
the correct answer is the option B about 45%
Answer:
x=67°
Step-by-step explanation:
Sum of all angles is 180°
36°+77°+x=180°
113°+x=180°
x=180°-113°
x=67°
Bro this is right answer plzzz mark me as brainliest★
