Answer:

It's acute triangle

Step-by-step explanation:

c^2 = 19^2 = 361

a^2 + b^2 = 15^2 + 13^2 = 225 + 169 = 394

c^ < a^2 + b^2 > . It's acute triangle

Answer:

Step-by-step explanation:

A triangular prism is a prism that has two triangular faces and three rectangular sides.

The area of the rectangular sides is A = lbh

A = area, l = length, and h = height.

The area of the triangular faces is A = 1/2bh

A = area, b = base, and h = height.

madreJ [45]

Answer:

$y =-\frac{3}{2}x + 6$

Step-by-step explanation:

Given

$y = []x + 6$ --- equation 1

$y = \frac{2}{3}x + 10$ --- equation 2

Required

Fill in the blank

A linear equation is represented as:

$y = mx + b$

Where m represents the slope

If (1) and (2) are perpendicular, then:

$m_1 = -\frac{1}{m_2}$

In $y = \frac{2}{3}x + 10$ --- equation 2

$m_2 = \frac{2}{3}$

So, we have:

$m_1 = -\frac{1}{m_2}$

$m_1 = -\frac{1}{2/3}$

$m_1 = -\frac{3}{2}$

Hence, the complete equation is:

$y =-\frac{3}{2}x + 6$

Answer:

$c=\sqrt{65}=8.062.$

Step-by-step explanation:

$\text{Consider } \bigtriangleup DBC, \text{by Pythagoras}\\DB^2+BC^2=DC^2 \\\Rightarrow b^2=DC^2-BC^2\\\Rightarrow b^2= 5^2-3^2=25-9\\\Rightarrow b^2= 16\\\text{Then } , b=4.\\ \text{Consider } \bigtriangleup DBA, \text{by Pythagoras}\\DB^2+BA^2=DA^2\\\Rightarrow c^2=b^2+BA^2\\\Rightarrow c^2=4^2+7^2\\\Rightarrow c^2=16+49\\\Rightarrow c^2=65\\\text{Then } , c=\sqrt{65}=8.062.$
