<span>−3(1.5n−1) is correct </span>
<h2>Answer:</h2>
49.2
<h3>Step by step explanation:</h3>
We know that,
a² - b² = (a+b)(a-b)
7.46² - 2.54² ↓
= (7.46 + 2.54)(7.46 - 2.54)
= (10)(4.92)
= 49.2 Ans.
Answer:
14.9 cm
Step-by-step explanation:
![\frac{ \sin(12) }{10} = \frac{150}{a} = \frac{ \sin(18) }{c} \\ c = \frac{10 \times \sin(18) }{ \sin(12) } = \\ c = \frac{3.09}{0.2079} = 14.86 = 14.9](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csin%2812%29%20%7D%7B10%7D%20%20%3D%20%20%5Cfrac%7B150%7D%7Ba%7D%20%3D%20%20%5Cfrac%7B%20%5Csin%2818%29%20%7D%7Bc%7D%20%20%20%5C%5C%20c%20%3D%20%20%5Cfrac%7B10%20%5Ctimes%20%20%5Csin%2818%29%20%7D%7B%20%5Csin%2812%29%20%7D%20%20%3D%20%20%5C%5C%20c%20%3D%20%20%5Cfrac%7B3.09%7D%7B0.2079%7D%20%20%3D%2014.86%20%3D%2014.9)
Answer:
B=45
Step-by-step explanation:
let the supplamentary angle of <A is <d
180-A=d
180-135=d
45=d
90+d+B=180
90+45+B=180
135+B=180
B=180-135
B=45
