Answer:
<em>HT </em>= 17
<<em>T</em> = 62°
<<em>H</em> = 28°
Step-by-step explanation:
1. Use the Pythagorean Theorem to find the length of the missing side.
a² + b² = c²
15² + 8² = c²
225 + 64 = c²
289 = c²
√289 = c
c = 17
The length of side HT is 17.
2. Use SOHCAHTOA to find the measure of <<em>T</em>. Since we know the measure of two sides, opposite (15) and adjacent (8), use the formula for tangent as tangent is opposite/adjacent.
Tangent =
=
= 1.875
Use the tan⁻¹ button on the calculator to find the value for <<em>T.</em>
tan⁻¹(1.875) = 61.9°
<<em>T = </em>62°
3. To find the measure of <<em>H, </em>you can either add up the two angles and subtract from 180° or use SOHCAHTOA.
90° + 61.9° + x = 180°
151.9° + x = 180°
x = 28°
or
We know two sides: opposite (8) and adjacent (15). So, we will use tangent.
Tangent =
=
= 0.5333333333
Take the tan⁻¹ to get the measure of <<em>H.</em>
tan⁻¹(0.5333333333) = 28.07 = 28°

Answer:
Step 1
Step-by-step explanation:
Associative property of addition is The order of the parentheses. There are no parentheses is this problem. We are using the commutative property of addition which states we can change the order of the addends
Hack
for y=ax^2+bx+c
the xvalue of the vertex is -b/2a
and the y value is found by subsituting that for x
so
-b/2a
h(t)=2x^2+4x+7
a=2
b=4
-b/2a=-4/(2*2)=-4/4=-1
the y value
h(-1)=2(-1)^2+4(-1)+7
h(-1)=2(1)-4+7
h(1)=2+3
h(1)=5
(-1,5) is da vertex
