For ΔABC, which two relationships are true?
Phoenix [80]

The two correct relationships are:

cos(\theta)=\frac{AB}{AC} = sin(90-\theta)\\\\sin(\theta)=\frac{BC}{AC} = cos(90-\theta)

<h3>What is a right-angled triangle?</h3>

The triangle shown is a right-angled triangle

Considering <(90-\theta)^o

cos(90-\theta)=\frac{BC}{AC} \\\\sin(90-\theta)=\frac{AB}{AC}\\\\tan(90-\theta)=\frac{AB}{BC}

Considering <\theta

cos(\theta)=\frac{AB}{AC} \\\\sin\theta)=\frac{BC}{AC}\\\\tan(\theta)=\frac{BC}{AB}

Comparing <\theta and <(90-\theta)^o, the true statements are:

cos(\theta)=\frac{AB}{AC} = sin(90-\theta)\\\\sin(\theta)=\frac{BC}{AC} = cos(90-\theta)

Mnenie [13.5K]
Line <span>–3x + 9y = 18
</span>
x-intercept when y = 0
so -3x = 18
        x = -6

y-intercept when x = 0
so 9y = 18
       y = 2

answer
x-intercept (-6,0)
y-intercept (0, 2)
