Mathematics
1 answer:
sergey [27]3 years ago
5 0

Answer:

927.0 cm²

Step-by-step explanation:

Step 1: find Z

m < Z = 180 - (28 + 118) (sum of ∆)

= 180 - 146

Z = 34°

Step 2: Find side XY using the law of sines

\frac{XY}{sin(34)} = \frac{42}{sin(28)}

Cross multiply

XY*sin(28) = 42*sin(34)

XY*0.469 = 42*0.559

Divide both sides by 0.469

\frac{XY*0.469}{0.469} = \frac{42*0.559}{0.469}

XY = 50.06

XY ≈ 50 cm

Step 3: find the area.

Area of ∆ = ½*XY*YZ*sin(Y)

XY ≈ 50 cm

= ½*50*42*sin(118)

= 25*42*0.8829

Area = 927.045

Area ≈ 927.0 cm² (nearest tenth)

25 – 4.33<br>7 + (1 - 100)​
Sidana [21]

Answer:

25 – 4.33 = 20.67

7 + (1 - 100)​ = -92

Step-by-step explanation:

First one) Simply use your knowledge of integers and decimals to solve this. You can even start by drawing a number line and practising with that before beginning to do harder problems.

Second one) Just like the first one but use PEDMAS, BEDMAS or BODMAS and make sure to solve the brackets first.
