Answer:
x = 55
Step-by-step explanation:
opposite angles are supplementary
125+x = 180
Subtract 125 from each side
125+x-125 = 180-125
x = 55
Answer:
Given:
- adjacent: 4 cm
- hypotenuse: x cm
- angle: 45°
<u>using cosine rule:</u>
Square of longest side = 17^2 = 289
15^2 = 225
13^2 = 169
total 394 289 is less than this so its acute
hello :
<span>help :
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x =
(-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions</span>
So in the number 58,927 your decimal point starts after the 7. When you move it to the left four places (four numbers) the decimal is now right after the 5. Your new answer is 5.8927. Hope I helped :D
