RQ² = RP² + PQ²

RQ² = 45² + 24²

RQ² = 2025 + 576

RQ² = 2601

RQ = 51

PT/PR = PQ/RQ

PT/45 = 24/51

PT = (24/51) × 45

PT = (8/17) × 45

PT = 360/17

Good morning ☕️

Answer:

Step-by-step explanation:

<u><em>trigonometry method:</em></u>

24÷45=0,533333333333

tan(m∠R) = 24/25

then

m∠R = tan⁻¹(0,533333333333)

=28,072486935838

sin(m∠R) = PT/45

then

PT = 45×sin(28,072486935838)

=21,176470588225

Problem<br> 1<br> + 10x + 13 = 4

lutik1710 [3]

Answer:

$x = -1$

Step-by-step explanation:

Equation: $1+10x+13=4$

Step 1: Balance both parts of the equation.

$1+10x+13=4$

$(10x)+(1+13)=4$

$10x+14=4$

Step 2: Reduce 14 from both parts of the equation.

$10x+14-14=4-14$

$10x= -10$

Step 3: Split both sides by 10, because $\mathrn {10x = -10}$ .

$\frac{10x}{10} = \frac{-10}{10}$

$10 / -10 = -1$

Therefore, x = -1.

Which expression is equivalent to 4+2(1+3x)

Leviafan [203]

Answer:

I'm glad you asked!

Step-by-step explanation:

OK,let's simplify the number for a equivalent expression.

$4+2(1+3x)$

Distribute:

$=4+(2)(1)+(2)(3x)$

$= 4+2+6x$

Combine Like Terms:

$=4+2+6x$

$=(6x)+(4+2)$

$=6x+6$

The Final Answer is : $6x+6$

Please help me because I need to turn this on tommorrow

Trava [24]

YAY I KNOW HOW TO DO THIS OKAY
so 90 degrees minus 49 degrees equals 41 degrees
then 41= (x+3) then you subtract 3
so x=38
