Helloo!!! please help me on this !!!!

ivann1987 [24]

It is given that ️PQR & ️UVW are congruent to each other. According to CPCT, the corresponding angles in 2 triangles willl have the same measure. So, ∠R = ∠W, i.e, (10x - 18)° = 8x°

$\mathfrak{10x - 18 = 8x}$

$\mathfrak{10x - 8x = 18}$

$\mathfrak{2x = 18}$

$\mathfrak{x = \dfrac{18}{2}}$

$\underline{\mathfrak{x = 9}}$

Measure of ∠R :

$\mathfrak{8x}$

$\mathfrak{8(9)}$

$\boxed{\mathfrak{72^{\circ}}}$

$6.7 \leq w \leq 7.3$

$w - 7 = -0.3$

$w = 6.7$

So the answer is

Plz help me Thx so much

Answer:

shipping and handling is 18.90 dollars

Step-by-step explanation:

percent means "per one hundred", so any percent can be written as a fraction over 100

30% = 30/100 = 0.30

Multiply 0.30 with the price 63 to get 0.30*63 = 18.90, which is the cost of shipping only. This result is added on top of the 63 dollars to get the total cost.
