Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°

Fake Question: Should Ujalakhan01 be a moderator? (If you could answer I'd appreciate it haha.)

Dovator [93]

Answer:

$a^9 + b^ 5 + c^{13}$

Step-by-step explanation:

$(a^5 \times a^4)+(b^2 \times b^3) + (c^7 \times c^6)$

When bases are same and it is multiplication, then add the exponents.

$(a^{5+4})+(b^{2+3})+(c^{7+6})$

$(a^9)+(b^ 5) + (c^{13})$

Apply rule : $(a^b)=a^b$

$a^9 + b^ 5 + c^{13}$

zlopas [31]

Answer:

The answer would be 2:30

Step-by-step explanation: lets say they both take 3 hours, that would mean that if they work together, that means they can cut their time by half,

but if jai is slower paced it and takes about 1 hour more, just add 1 hour to the hour and 30 to be able to get 2:30

pls give brainliest.
