Answer:
32in^2
Step-by-step explanation:
1. you find the area of the triangles, which are all equal:
4*2/2 = 4. 4*4 = 16
2. find area of square:
4*4 = 16
3. add them together:
16+16 = 32
Answer:
5.6 = AB
Step-by-step explanation:
Since this is a right triangle, we can use trig functions to find the length of AB
Cos theta = opp side/ hypotenuse
cos 62 = AB / BC
cos 62 = AB /12
Multiply each side by 12
12 cos 62 = AB
5.633658753 = AB
Rounding to 1 decimal place
5.6 = AB
We can also find AC
sin theta = opp side/ hypotenuse
sin 62 = AC / BC
sin 62 = AC /12
Multiply each side by 12
12 sin 62 = AC
10.59537111 = AC
Rounding to 1 decimal place
10.6 = AC
Answer:
120°
Step-by-step explanation:
All triangles are equal to 180° so you would subtract the total (180) from the given
Answer:
10.0cm
Step-by-step explanation:
<span>3t – 6t + 8 – 7t = – 2
Simplify and combine Like-Terms
</span><span><span><span>3t + −6t + 8 </span>+ </span>− 7t </span>= <span>−<span>2
</span></span><span><span>(<span><span>3t+<span>−6t</span></span>+<span>−7t</span></span>) </span>+ (8) </span>= <span>−<span>2
</span></span><span><span>−10t </span>+ 8 </span>= <span>−<span>2
Subtract 8 from each side
</span></span><span><span><span>−<span>10t </span></span>+ 8 </span>− 8 </span>= <span><span>−2 </span>− <span>8</span></span>
-10t = -10
Divide each side by -10
-10t ÷ -10 = -10 ÷ -10
t = 1
