Answer:

x=4

y=3

Step-by-step explanation:

-0.8x+1.3y=0.7,3.2x−2.5y=5.3

-0.8x+1.3y=0.7

x=−1.25(−1.3y+0.7)

x=1.625y−0.875

3.2(1.625y−0.875)−2.5y=5.3

5.2y−2.8−2.5y=5.3

2.7y−2.8=5.3

2.7y=8.1

y=3

x=1.625×3−0.875

x= 39-7

x=4

10th grade geometry Help!!!

Airida [17]

Answer:

m∠W = (4x)° = 4 × 18 = 72°

m∠Y = (3x)° = 3 × 18 = 54°

m∠Z = (3x)° = 3 × 18 = 54°

Step-by-step explanation:

m∠W = (4x)°

m∠Y = (3x)°

m∠Z = (3x)°

i.e.,

We Know That,

The sum of a Triangle is 180°

So,

m∠W + m∠Y + m∠Z

i.e.,

(4x)° + (3x)° + (3x)° = 180°

10x° = 180°

x = 180/10

x = 18°

Now,

m∠W = (4x)° = 4 × 18 = 72°

m∠Y = (3x)° = 3 × 18 = 54°

m∠Z = (3x)° = 3 × 18 = 54°

Thus, x = 18°

<h3>FOR VERIFICATION ONLY:</h3>

(4x)° + (3x)° + (3x)° = 180°

4 × 18 + 3 × 18 + 3 × 18 = 180

72° + 54° + 54° = 180°

180° = 180°

Hence, L.H.S = R.H.S
