Answer:
t=16
Step-by-step explanation:
you have to change the numbers to get just the variable.
we start from -3.
5=t/2-3
8=t/2
(we multiply by 2 instead of dividing)
8×2=16
t=16
Answer:
The Proof for
△ABD ≅ △CBD is below
Step-by-step explanation:
Given:
AD = CD .........BD bisect AC
To Prove:
△ABD ≅ △CBD
Proof:
In ΔABD and ΔCBD
BD ≅ BD ....……….{Reflexive Property}
∠ADB ≅ ∠CDB …………..{Measure of each angle is 90°( )}
AD ≅ CD ....……….{ }
ΔABD ≅ ΔCBD .......….{By Side-Angle-Side Congruence test} ...Proved
Answer:
A little over 31hours
Step-by-step explanation:
Use simple proportion
58miles = 1hr
1805miles = ?
(1805x1)/58 = 31.12hrs
Since the question asks you for an estimation, it should be fine to say a little over 31hours but do show full working and the accurate answer
The two unknown sides are equal to each other so then the two unknown angles are also equal.
A triangle angles add up to 180
36 + 2x = 180
2x = 180 - 36
2x = 144
unknown angles x = 72°
draw line down center of triangle to make two right triangles with side 22/2 = 11. SOH CAH TOA
cos(72) = 11/H
H = 11/cos(72)
H = 35.6
perimeter = 22 + 2(35.6)
perimeter = 93.2 cm
answer E .
