Answer:
The perimeter of the triangle is equal to 36 cm
Step-by-step explanation:
we know that
The inscribed circle contained in the triangle BCA is tangent to the three sides
we have that
BF=BH
CF=CG
AH=AG
step 1
Find CG
we know that
CF=CG
so
CF=7 cm
therefore
CG=7 cm
step 2
Find AG
we know that
CA=AG+CG
we have
CA=15 cm
CG=7 cm
substitute
15=AG+7
AG=15-7=8 cm
step 3
Find AH
Remember that
AG=AH
we have
AG=8 cm
therefore
AH=8 cm
step 4
Find BF
Remember that
BF=BH
BH=3 cm
therefore
BF=3 cm
step 5
Find the perimeter of the triangle
P=AH+BH+BF+CF+CG+AG
substitute the values
P=8+3+3+7+7+8=36 cm
Hi there,
your question is asking for the angle of the central circle, and the formula is: the two arcs' sum divided by 2
So,
(60 + 40) ÷ 2 = 50
The answer is 50°
Hope I helped :p
THats all i could come up with nothin mor nun less
Same Sides
When the sides are the same then the triangles are congruent. because they all have exactly the same sides. because the two triangles do not have exactly the same sides.
24,812(.04)=992.48
24,812 + 992.48= 25,804.48
Answer:
B
Step-by-step explanation:
yes, 12² + 13² = (
)²
144 + 169 = 313
313 = 313
